HTTP::Headers::Fast(3pm)

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.

psgi_flatten
    returns PSGI compatible arrayref of header.

        my $headers:ArrayRef = $header->flatten

psgi_flatten_without_sort
    same as flatten but returns arrayref 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';
