# NAME

HTTP::Headers::Fast - faster implementation of HTTP::Headers

# SYNOPSIS

    use HTTP::Headers::Fast;
    # and, same as HTTP::Headers.

# DESCRIPTION

HTTP::Headers::Fast is a perl class for parsing/writing HTTP headers.

The interface is same as HTTP::Headers.

# WHY YET ANOTHER ONE?

HTTP::Headers is a very good. But I needed a faster implementation, fast  =)

# ADDITIONAL METHODS

- as\_string\_without\_sort

    as\_string method sorts the header names.But, sorting is bit slow.

    In this method, stringify the instance of HTTP::Headers::Fast without sorting.

# @ISA HACK

If you want HTTP::Headers::Fast to pretend like it's really HTTP::Headers, you can try the following hack:

    unshift @HTTP::Headers::Fast::ISA, 'HTTP::Headers';
