# 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';
