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';
