Changes to squid-1.1.22 (June 25, 1998):

	- Fixed hash4() for SCO cc (Vlado Potisk).
	- Fixed aclParseIpList() for SPLAY trees.
	- Fixed comm_poll() to deal with ERESTART errors.
	- Fixed icpSendMoreData() buffer overrun bug
	  for HEAD requests.
	- Added Mike Pelletier's connect retry code.
	- Fixed daylight savings time bugs (again).
	- Added .readme to include/mime.table
	- Fixed likely year-2000 bug in ftpget's timestamp
	  parsing (Henrik Nordstrom).
	- Fixed HTTP reply code for access denied messages (was 400,
	  now 403).
	- Added 'no_cache' ACL support (Stephen Griffin).

Changes to squid-1.1.21 (March 17, 1998):

	- Fixed ftpget's "Generated" timestamp trailer on error
	  messages (Oskar Pearson).
	- Count (in the client_list database) DENIED ICP queries
	  occuring after the 95% threshold, even though we don't
	  transmit an ICP reply.
	- Fixed bug causing 'ipcache_purgelru()' to be added to
	  the event queue multiple times.
	- Added ipcache and fqdncache average service times to
	  cachemgr 'info' page.
	- Fixed ACL parsing of hostnames to use all IP addresses,
	  not just the first.
	- Fixed how we handle ICP replies to misconfigured neighbors.
	  Instead of cutting off at the first 100 ICP_DENIED replies, we
	  now start sending replies again after ignoring them for 1
	  hour.  This should cause the other cache to detect the
	  excessive ICP_DENIED replies and disable itself.
	- Changed sorting order for compareSize().  Apparently we were
	  sorting in order of smallest to largest, when we really want to
	  sort the other way when removing in-mem objects.
	- Changed storeShouldPurgeMem() to use the high water mark
	  instead of the low water mark.
	- If a deny_info URL has 'cgi' in it, then append CGI args for
	  client's IP address, requested URL, and the denying cache.
	- Added configure check for broken setresuid().
	- Updated contrib/nextstep directory (Gerben Wierda).
	- Changed acl.c to check "unescaped" versions of URLs so
	  that URL-escaping does not bypass access controls.
	- Fixed double-call bug (and comm_remove_close_handler
	  coredump?) for POST and SSL requests.
	- Give the Host: header a higher precedence that the socket
	  IP address for transparent proxying (Henrik Nordstrom).
	- Don't call ntohl() conversion on ICP message 'shostid'
	  field.
	- Changed netdb structure so its easier to move hosts from one
	  network to another.
	- Fixed incorrect comparison order for store.c::compareSize()
	  (Li Fan).
	- Changed storeShouldPurgeMem() to check the in-memory
	  high water mark instead of the low (Li Fan).

Changes to squid-1.1.20 (January 9, 1998):

	- Changed default 'average_object_size' to 13 KB.
	- Changed number of allocated file numbers to twice
	  the number estimated.
	- Changed file_map_allocate() to not coredump when the filemap
	  list becomes full.  Instead, a warning is logged and new
	  objects will not be saved until some swap files become
	  available.
	- Year-2000 fixes (Arjan de Vet).

Changes to squid-1.1.19 (December 18, 1997):

	- Applied David Luyer's TCP retry algorithm: Give a parent (or
	  peer) cache 10 chances before marking it truly dead, as soon
	  as it fails the first time fire off a connection attempt and
	  if that succeeds mark it back with 10 fresh chances.
	- Re-fixed handling long lines in Gopher replies (John Line).
	- Fixed dereference bug in BIN_TREE version of
	  aclMatchDomainList().
	- Added Date: and Expires: to proxy-auth message.
	- Fixed using Proxy Auth and User based ACLs without any ident
	  lookups; the ident field of the aclChecklist was never filled
	  (Milton Ngan).
	- Updated contrib/nextstep directory from Gerben Wierda.
	- Added ability to generate HTTP redirect messages from
	  the redirector output by prepending "301:" or "302:" to the
	  new url.  See FAQ 4.16 for more details.
	- Fixed errorpage.c buffer overrun.
	- Changed storeInit() to allocate 1.5 times the estimated number
	  of cache objects for the 'filemap' bitmap.

Changes to squid-1.1.18 (October 31, 1997):

	- Added fix for missing S_ISDIR macro on NEXTSTEP (Gerben Wierda).
	- Fixed another ftpget content type bug (Yoshitane Tachibana)
	- Fixed ftpget to handle EALREADY from non-blocking connect().
	- Added ALLOW_HOSTNAME_UNDERSCORES option from Ron Gomes.
	- Fixed bugs which allowed 302 Temporary Redirects to be cached.
	- Fixed DST offset bug in parse_rfc1123().
	- Fixed NEIGHBOR_CLOSEST_ONLY define which had the same value as 
	  NEIGHBOR_MCAST_RESPONDER.
	- Fixed handling long lines in Gopher replies (John Line).

Changes to squid-1.1.17 (October 19, 1997):

	- Fixed ftpget null pointer coredump for mime encodings.
	- Fixed setuid() bug when creating swap directories.  Now
	  change to 'effective_user' before making dirs.
	- Fixed cachemgr.cgi to give 'unknown host' message if
	  gethostbyname() fails.
	- Fixed extra disk read() bug for swapins.  Now a disk
	  read calls back immediately if any data was read instead
	  of trying to fill the 8k buffer.
	- Fixed asciiHandleConn().  The 'while (1)' loop broke things
	  badly under very high loads.  Limit to 10 times through
	  the loop, or until RESERVED_FD limit is reached.

Changes to squid-1.1.16 (August 25, 1997):

	- Added while loop around accept() (Michael O'Reilly).
	- Exit if parseKilobytes() overflows (e.g. maximum_object_size).
	- Added 'closest-only' cache_host option to accept only
	  CLOSEST_PARENT_MISS but not FIRST_PARENT_MISS.
	- Fixed ftpget to escape special characters in HTML output.
	- Fixed ftpget to take the second-level filename extension
	  content-type for 'x-gzip' and 'x-compress' encodings.
	- Changed ftpget to check for whitespace in Windows listings
	  (R. Scott Bailey).
	- Fixed long URL coredump problem from the new 'log_url' scheme.
	- PROXY_AUTH passwd security fix (David Luyer).

Changes to squid-1.1.15 (August 11, 1997):

	- Fixed bug in diskHandleWrite().  'break' should be 'continue'
	  (Michael O'Reilly).
	- Fixed a storeDoRebuildFromDisk() bug; needed to check for
	  swapfile < 0 earlier.
	- HEAD requests should not be given to passStart() (Taketo Kabe).
	- Generate an 'INVALID URL' error if a hostname contains
	  illegal characters.
	- Added keyword 'all' for inside_firewall option (Javier Achirica).
	- Fixed logging of wrong URL for requests changed by a
	  redirector.
	- Added first-cut RELOAD_INTO_IMS feature.  #ifdef'd to
	  protect the innocent.
	- Fixed comm_select() to only check stall_delay for read
	  handlers (Peter Wemm).
	- IMPORTANT change to the -z option: Numerous people have lost
	  their cache contents because Squid would automatically wipe
	  out the cache if one of the cache directories did not exist.
	  Squid will no longer do this.  Now, Squid tests all the
	  'cache_dir' directories and all of the first-level swap
	  directories underneath then.  If one of those directories
	  does not exist, Squid exits and writes a message to stderr
	  and to cache.log.  The message tells the administrator to run
	  'squid -z' to create the swap directories, or to manually fix
	  the problem.   This means that you must manually run 'squid -z'
	  when setting up Squid for the first time.
	- Fixed IP cache bug with popular hostnames which lose all
	  their addresses to ipcacheRemoveBadAddr().  In 1.1.12 we
	  required that IP cache entries could only be released if not
	  referenced for one minute.  However, some names are so
	  popular that they would never get released.  Now we also
	  require that i->addrs.count > 0 if we're NOT going to release
	  the expired entry (Joe Ramey).

Changes to squid-1.1.14 (July 11, 1997):

	- Another try at log_url crap.  Added icpState->log_url
	  member.  Set mem_obj->log_url in new_MemObject() which
	  means passing more args to storeCreateEntry().  Also added
	  urlClean() which calls urlParse(); needed for ICP logging.
	- Clean URLs will be truncated at '?' if present.
	- Give fd_note() the clean URL.

Changes to squid-1.1.13 (July 9, 1997):

	- Fixed storeLog() coredump on mem->log_url.
	- Fixed string bounds bug if a redirector returns a short
	  hostname which require appending 'append_domain' (David
	  Lamkin).
	- Added 'fake_user_agent' to configuration because HTTP
	  anonymizing strips the User-Agent which some servers require.

Changes to squid-1.1.12 (July 5, 1997):

	- Fixed dnsserver buffer overflow bug and other problems related
	  to long, bogus domain names.
	- Fixed occasional incorrect ERR_DNS_FAIL errors caused when
	  an IP cache entry gets released about the same time an
	  ICP query timeout occurs.
	- Fixed setrlimit() bugs seen on DUNIX 4.0; rl.rlim_max == 0.
	- Only strip 'Proxy-authorization' header when USE_PROXY_AUTH
	  is defined and proxy_auth is configured (Ron Gomes).
	- Added missing calls to reset socket timeouts for SSL
	  and passthrough requests.
	- Fixed "Available number of file descriptors" value in
	  cachemgr info output.
	- Fixed coredump in proxyAuthenticate() if password file
	  has an entry with only a user name (Jordan Hrycaj).
	- Security patch for usernames and passwords in URLs.
	  + ftpget would insert a BASE URL including the username and
	    password for directory listings IF the original request did
	    NOT include the the trailing slash.  This could be disabled
	    with a command line option, but is enabled by default.  Now
	    its #ifdefd out.
	  + Usernames and passwords could be logged to access.log and
	    store.log.  Now a new element,
	    StoreEntry->MemObject->log_url, holds a copy of the requested
	    URL without the name and password.  This isn't 100% fixed yet
	    because log_url gets generated when the StoreEntry gets
	    created.  If the StoreEntry never gets created, then the URL
	    with name and password will get logged.  Also, the name and
	    password are not stripped from ICP requests.  Also, this
	    changes store.log.  Previously we logged StoreEntry->key
	    which would look different than the URL for private entries,
	    but now we'll always log the URL.
	  + Finally, we now set REQ_AUTH for any request that includes a
	    name or password.  This prevents the request from being
	    cached (!) and prevents it from being sent to neighbor
	    caches.  In other words, its treated just as if an
	    Authorization request header were present.
	- Fixed Byte-Range handling so that valid, whole objects
	  are not released.

Changes to squid-1.1.11 (June 14, 1997):

	- Clean up NeXTStep compiler warnings (Karsten Heinze, Ed Knowles).
	- Don't forward 'Proxy-Authorization' headers (Chris Pascoe).
	- Fixed up Host: header parsing (Henrik Nordstrom).
	- Changed DefaultObjectsPerBucket to 20 in cache_cf.c.
	- Fixed parsePathname() bug for magic word "none".
	- Fixed ipcache_release to rename entries which get stuck with locks.
	- Fixed "eventDelete(peerCheckConnect, e);" bug when the DNS lookup
	  is pending.
	- Add sys/types.h to lib/safe_inet_addr.c for NeXTSTEP (Timo
	  Hennerich).
	- Fixed cur_len decrement bug in diskHandleRead()
	  (Michael O'Reilly).
	- Added contrib/rredir.pl from Peter Eisenhauer.
	- Always forward requests with 'Byte-Range' headers (Ron Gomes).
	- Fixed StoreEntry client offset bug which could trigger a
	  fatal_dump().
	- Fixed noticing that dnsservers have shut down during restart.
	- Added contrib/nextstep installer package from Gerben Wierda.
	- Modified storeDirClean() to remove swap files where the
	  number is being used, but the file is in the wrong directory.
	- Allow PURGE method on all protocols.
	- Added 'icp_hit_stale' option.
	- Fixed proxy auth refresh bug (Chris Pascoe).
	- Don't check for other filename extensions if an FTP URL
	  ends with .txt (Ed Knowles).
	- Relocated ERR_NO_CLIENT_BIG_OBJ check to eliminate incorrect
	  (but harmless) error message.

Changes to squid-1.1.10 (April 24, 1997):

	- Require 0 <= multicast ttl <= 128.
	- Changed 'unsigned int inaddr_none' to 'struct in_addr no_addr'.
	- Added debug_trap() if unlocking a StoreEntry which still 
	  has registered clients.
	- Added missing storeUnregister() calls.
	- Fixed storeClientListAdd() bug of adding same FD twice.
	- Fixed reconfigure/SIGHUP to wait 'shutdown_lifetime' seconds
	  after receiving signal (Ron Gomes).
	- Added missing commSetSelect() in icpDetectClientClose()
	  (Mark Treacy).
	- Fixed multicast group member counting bug with fake
	  StoreEntry's.
	- Only enable ICP_FLAG_SRC_RTT if the peer is ICP_VERSION_2.
	- Fixed compiling unlinkd in a separate directory (Assar Westerlund).
	- Fixed comm_select_incoming SEGV for poll() version when using
	  udp_{incoming,outgoing}_address  (Mark Treacy).
	- Fixed some SIGHUP related memory problems with redirectors,
	  ipcache, and fqdncache, and peerCountMcastPeers*().
	- Make the unlinkd and pinger programs configurable (Ron Gomes,
	  Neil Murray).
	- Add handshake to unlinkd program (Ron Gomes).
	- Exit if a configured program doesn't exist (Neil Murray).
	- Abort if unlinkd fails to start (Ron Gomes).
	- Added -m option to ftpget for defining default MIME type.
	  (Neil Murray).
	- Optimized comm_select() functions (Mark Treacy).
	- Fixed ipcache_release() to not release locked entries;
	  instead expire them immediately.
	- Fixed up rebuild code to handle swapfile/URL clash
	  cases better.
	- Added safe_inet_addr() to protect from bogus IP addresses
	  (Arjan de Vet).
	- Fixed handling of ssl_proxy and passthrough_proxy when not
	  behind a firewall.


Changes to squid-1.1.9 (March 30, 1997):

	- Fixed aclIpNetworkCompare for USE_SPLAY_TREE; was applying
	  netmask to non-local variable through pointer.  (Ansgar
	  Hockmann).
	- Fixed cachemgr bug incorrectly assigning connect() return
	  value (Nigel Metheringham).
	- Fixed diskHandleWrite bug: not setting write_daemon = PRESENT.
	- Fixed situation where all requests would be handled by
	  "single parent" and other peers would never be queried
	  again.
	- Fixed ftpget bug causing program to continue after printing
	  usage.
	- Changed 'reference_age' to be the maximum for the dynamcially
	  computed value (Mark Treacy).
 	- Added external 'unlinkd' process to unlink swap files.
	- Added more dnsserver status information to cachemgr output.
	- In httpReadReply: extend FD lifetime only after successful
	  read, not every read.
	- In httpBuildRequestHeader: link size of 'ybuf' to MAX_URL.
	- Added routines to count number of members of each multicast
	  peer.
	- Fixed multicast ICP bug causing unnecessary timeouts.
	- Added error messages if setuid/setgid functions fail.
	- Added non-POSIX tempnam.c replacement for NeXTStep (Gerben
	  Wierda).
	- Removed redundant file:// --> ftp:// check (Willy TARREAU).
	- Removed check for reply->code == 200 in icpGetHeadersForIMS().
	- Fixed IP cache bug which caused 'dns_children 0' to break;
	- Deny access to dangerous TCP ports (7, 9, 19).
	- Removed single-line functions: fdstat_biggest_fd(),
	  comm_get_fd_lifetime(), comm_get_fd_timeout().
	- Removed storeCheckExpired() from storeGetSwapSpace() as
	  likely cause of slowing down cache when exceeding the high
	  water mark.
	- Fixed storeCheckExpired() to not always check the
	  LRU expiration age (Mark Treacy).
	- Lowered 'store_objects_per_bucket' to 20 so that
	  storeMaintainSwapSpace() runs frequently enough to 
	  keep up with incoming objects.
	- Fixed FTP to use the Authorization header only when the
	  usernames match.
	- Fixed another continuation-lines-not-starting-with-NNN bug
	  in ftpget.
	- Added 'client_db' config option to disable keeping statistics 
	  for each client address.
	- Added support for using ICMP data stuffed into ICP replies
	  for peer selection algorithm.  Enable with 'query_icmp'
	  in squid.conf.
	- Fixed net_db design bug where _net_db_peer structures pointed
	  to 'peer' structures that get freed and reallocated during a
	  reconfigure.
	- Moved comm.c fd_lifetime[] array into FD_ENTRY structure.
	- Cleaned up storeCopy().  debug_trap on requested offset <
	  e_lowest_offset.
	- Cleaned up fdstat_init() and fdstat_update().
	- Cleaned up ftp_login_parser().

Changes to squid-1.1.8 (March 3, 1997):

	- Fixed neighborsUdpAck() coredump bug for source-ping and
	  non-peer ICP replies.
	- Prevent ipcache_gethostbyname from changing an IP_DISPATCHED
	  entry to IP_CACHED; fqdncache too.
	- Made send_announce non-blocking.

	  background and don't mark the peer as 'up' until a connection
	  succeeds.
	- Okay to increase FD_SETSIZE on FreeBSD 2.2.x (Peter Wemm).
	- Fixed HTTP anonymizer bug in 'standard' mode.
	- Fixed aclMatchDomainList() coredump for unresolvable addresses.
	- Changed default disk low/high water marks to 90/95%.
	- Prevent ftpget buffer overflow (Riku Saikkonen).

Changes to squid-1.1.7 (February 25, 1997):

	- Fixed non-default port numbers for FTP URLs (John Saunders).
	- Fixed urlParse to leave trailing slashes on FTP URLs.  Although
	  stripping the slashes offers a slight hit rate increase, it
	  breaks some proxies which return HTTP redirects.
	- Initialize struct tm in parse_rfc1123() (Henrik Hempelmann).
	- Fixed parseHttpRequest() to use memcpy instead of strncpy;
	  caused POST's with NULL bytes to fail (Joe Ramey).
	- Fixed another HTTP reply code 0 bug (Neil Murray).
	- Changed code structure in ipcache_nbgethostbyname() to
	  maybe get around some trashed-stack problems.
	- Added WARNING if blocking gethostbyname() gets called.
	- Fixed calling commSetSelect() with FD < 0 bug in ssl.c and
	  pass.c.
	- Moved 'append_domain' operation to urlParse().
	- Fixed too many arguments bug in diskHandleWrite, caused
	  coredumps when write fails (due to full disk).
	- Fixed extra unlocking on partial reads from dnsservers.
	- Fixes for 'Splay' trees in acl.c (Ed Knowles)
	- Support for balanced binary trees in acl.c (Arjan de Vet).
	- Made HTTP anonymizing a standard feature and settable in
	  squid.conf (disabled by default).
	- Ignore ICP_MISS replies from multicast-responding parents
	  which would violate the domain restrictions.
	- Fixed another diskHandleWrite coredump bug when freeing
	  list of pending blocks.
	- Added support for 'src' ACLs in cache_host_acl lines.
	- Fixed ftpget bug when PASV connect times out.
	- Fixed adding duplicate IP cache entry for failed BLOCKING lookups.
	- Changed peer IP addresses (for ICP) to be refreshed every hour.

	- Merged squid-1.1.6 changes.

Changes to squid-1.1.6 (February 7, 1997):

	- Fix redirector to make sure the redirector child process is 
	  is alive and not busy before using it (Brent Foster).
	- Fixed ACL joining bug.
	- Fixed up support for multicast; see Release Notes for 
	  details.
	- Fixed ftpget to properly handle multi-line replies that
	  don't begin with "NNN-".
	- Changed store maintenance to randomize bucket order
	  each time after completion.
	- Set RLIMIT_VMEM to the maximum.
	- Syntax change: "edge" to "peer" everywhere.
	- Change redirector stats to also show number of rewritten
	  requests (Andrew Humphrey).
	- Changed HTTP anonmyizing to remove 'denied' headers
	  by default.  Define USE_PARANOID_ANONYMIZER to only pass
	  'allowed' headers instead (Bernd Ernesti).
	- Added 'Splay' trees (in #ifdefs) for fast IP access checking
	  (Ed Knowles).
	- Fixed 'COMM_INPROGRESS' typo bug (Balint Nagy Endre).
	- Added support for PURGE method to remove cached objects.
	- Upgraded scripts/check_cache.pl for v1.1 (Bertold Kolics).
	- Fixed announcement file descriptor leak (Balint Nagy Endre).
	- Fixed [^0-9] sscanf bug for some compilers (Jim Carroll).
	- Upgrade to autoconf-2.12
	- Added 'dns_defnames' option to allow dnsserver to interpret
	  single-component hostnames.
	- Refuse to run as root without defining 'cache_effective_user'.

Changes to squid-1.novm.5 (February 6, 1997):

	- Fixed stuck objects (and FD leak) due to not unlocking
	  objects in storeAbort().
	- Merged squid-1.1.5 changes.

Changes to squid-1.1.5 (January 22, 1997):

	- Fixed ACL parsing to join ACL entries with the same name
	  (Markus Stumpf).
	- Fixed BIT_SET/BIT_TEST typo in getDefaultParent() (Ed Knowles).
	- Removed comm_read() and commHandleRead().

	- Added .rpm MIME type (Nigel Metheringham).
	- Changed storeDirClean() to create missing directories.
	- Removed icpState->buf and storeCopy() call in icpGetHeadersfForIMS().
	- Fixed *_ip_list parsing bug (Hiroyuki Inoue).
	- Fixed bad comm_write() calls in passStart() and sslStart()
	  (Martin Boening).
	- Changed storeMaintainSwapSpace() to scan hash table buckets in
	  random order.
	- Added dynamic LRU Age expiration feature.  Expiration age is
	  calculated as a function of store_swap_size so that object
	  deletion rate matches the addition rate and we avoid emergency
	  object purge mode.

Changes to squid-1.novm.4 (January XX, 1997):

	- Fixed storeRegister loop in icpHandleIMSReply().
	- Merged squid-1.1.4 changes.

	- Created USE_GNUREGEX define to fix forcing GNU regex on 
	  Solaris and NeXTStep.
	- Changed SQUID_MAXFD to be a C variable.
	- Added QUICKSTART file.

	  (Hiroyuki Inoue).
	- Added 'udp_hit_obj_size' option (Mark Treacy).
	- Fixed cachemgr.cgi to print 'NEVER' instead of '27Y ago'.

	- Handle unexpected data from a redirector (Brent Foster).

Changes to squid-1.novm.3 (January 7, 1996):

	- Merged squid-1.1.3 changes.

Changes to squid-1.novm.2 (January 7, 1996):

	- Mega changes to make Squid not store objects in VM.

Changes to squid-1.1.3 (January 7, 1997):

	- Changed inet_addr("X") to inet_addr("255.255.255.255")
	  (Dan Riley).
	- Fixed matchInsideFirewall() bug when using 'firewall_ip' but
	  not 'inside_firewall' (Tai Jin).
	- check for text == NULL in icpSendERROR().
	- Don't make inaddr_none static in ftpget.c (Davide Migliavacca).
	- Fixed ipcache FMR bug for long-pending requests.
	- Fixes for NeXTSTEP 3.3 (Tethpub Znek).
	- add storeWriteCleanLog() call in fatal().

Changes to squid-1.1.2 (December 18, 1996):

	- Fixed (negative) caching of HTTP objects witch consist of
	  only some HTTP headers.
	- Fixed up SSL neighbor selection algorithm to be just
	  like the one in pass.c.
	- Fixed incorrect squid.conf comment about setting an objcache
	  password to 'none'.  Added keyword 'disable' to disable an
	  objcache function (Markus Gyger).
	- Further Cache.Announce.on fixes (Ernest Yik).
	- Add theOutIcpConnection to comm_select_incoming() for improved
	  ICP performance (Stewart Forster).
	- Added access.log documentation to Release-Notes-1.1.txt
	- Added support for TRACE method.
	- Added 'log_icp_queries on|off' to config (David Luyer).
	- Added hierarchy tag to common HTTP format access.log (David Luyer).
	- Moved second SQUID_MAXFD/FD_SETSIZE check to after #includes.
	- Added reverse DNS lookups for 'dstdomain' ACLs when the URL
	  contains an IP address.
	- Made HTTP reply header parsing more robust to deal with
	  bad 304 replies from squid-1.1.beta27 and earlier.
	- Changed reqnum passed in ICP replies to encode request method
	  in high byte.
	- Fixed neighbor round-robin bug (Uwe Doering).
	- Calculate accurage percentages for ICP and HTTP requests in

	  getting set (e.g. for requests matching hierarchy_stoplist).
	  This could cause multiple calls to storeAbort() for the same
	  entry.
	- With ENTRY_DISPATCHED now fixed, call squid_error_entry()
	  from protoUnregister() for StoreEntries which have not
	  been dispatched.
	- Fixed 'quick_abort' parsing bug.

	  just after an object retrieval begins.
	- Includes all squid-1.0 changes up to squid-1.0.10.
	- Added patch from srb@cuci.nl (Stephen R. van den Berg) for

	  and IMS-GET).
	- Added a function to verify content-lengths.  Objects with
	  mismatched (but non-zero) content lenghts will be ejected.
	- Added clean shutdown mode.  On SIGTERM the incoming HTTP socket
	  is closed.  Active clients are given a lifetime of 30 seconds
	  (configurable).  Process exits when all sockets are closed.
	- Added support for large POST objects.
	- Added "store.log" which logs RELEASE/SWAPIN/SWAPOUT events.
	- Added announce feature to squid; no longer external program.
	  If enabled, a running cache will announce itself every 24 hrs.
	- Added support for FTP URLs with non-default ports.
	- Added new Access Control List scheme.
	- Added Forwarded: header to proxy HTTP requests (HTTP/1.1 feature).
	- Added weights neighbors.
	- Added urlParse() which strips off default ports and 
	  makes hostnames all lowercase.
	- Added (section,level) debugging and 'debug_options' config line.
	- Added 'pid_filename' to configuration file.
	- Added 'visible_hostname' to configuration file.
	- added 'ftp_user' to configuration file.
	- added 'dns_positive_ttl' to configuration file.
	- added 'dns_negative_ttl' to configuration file.
	- Added 'shutdown_lifetime' to configuration file.
	- Fixed bug where cache process would "spin" on large objects
	  being deferred.
	- Fixed byte order conversion bug on setting echo port.
	- Changed meaning of command line -b (buffered logs) option.
	  Now the default behaviour is unbuffered logs, use -b to make
	  them buffered.
	- Changed WAIS code to always be fully compiled in.
	- Changed the storage manager to use the notion of private and
	  public keys.  Requests are now private until the reply headers
	  have been read.
	- Changed access logging significantly.  Entries to "access.log"
	  are written when the client connection closes.  Every connection
	  is logged exactly once, always with a valid size.
	- Changed access log format (non-common) to include request
	  method and sub-second timestamps.
	- Changed handing of ECONNRESET (connection reset) errors.
	  Now treated like any other read error.
	- Changed 'rotate logs' to be activated by SIGUSR1.
	- Changed configure script to look specifically for tm_gmtoff
	  and set HAVE_TM_GMTOFF.
	- Changed configure script to look specifically extended mallinfo
	  structure and set HAVE_EXT_MALLINFO
	- Changed ICP reply code to use negative TTL value as UDP_HIT
	  threshold so we never return a HIT on neg-cached objects.
	- Changed ftpget to use select(2) on I/O for timeouts.  ftpget
	  now exits immediately if stdin goes away.
	- Changed handling of '-z' option.  Now only execute 'rm -rf ...' if
	  -U option also given.
	- Removed the command line -d (debug) option.  Use 'debug_options'
	  in config file.
	- Removed all code and references to binary port.
	- Removed dual logging to stderr/cache.log.
	- Removed old IP access controls ('proxy_allow', etc.)
