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';
