#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';
