NAME

       CGI::Cookie::Splitter - Split big cookies into smaller ones.

VERSION

       version 0.05

SYNOPSIS

           use CGI::Cookie::Splitter;

           my $splitter = CGI::Cookie::Splitter->new(
               size => 123, # defaults to 4096
           );

           @small_cookies = $splitter->split( @big_cookies );

           @big_cookies = $splitter->join( @small_cookies );

DESCRIPTION

       RFC 2109 recommends that the minimal cookie size supported by the client is 4096 bytes.
       This has become a pretty standard value, and if your server sends larger cookies than that
       it's considered a no-no.

       This module provides a pretty simple interface to generate small cookies that are under a
       certain limit, without wasting too much effort.

METHODS

   new
           $splitter = CGI::Cookie::Splitter->new(%params)

       The only supported parameters right now are "size". It defaults to 4096.

   split
           @cookies = $splitter->split(@cookies)

       This method accepts a list of CGI::Cookie objects (or lookalikes) and returns a list of
       CGI::Cookies.

       Whenever an object with a total size that is bigger than the limit specified at
       construction time is encountered it is replaced in the result list with several objects of
       the same class, which are assigned serial names and have a smaller size and the same
       domain/path/expires/secure parameters.

   join
           $cookie = $splitter->join(@cookies)

       This is the inverse of "split".

   should_split
           $splitter->should_split($cookie)

       Whether or not the cookie should be split

   mangle_name_next
           $splitter->mangle_name_next($name)

   mangle_name
           $splitter->mangle_name($name, $index)

   demangle_name
           $splitter->demangle_name($mangled_name)

       These methods encapsulate a name mangling scheme for changing the cookie names to allow a
       1:n relationship.

       The default mangling behavior is not 100% safe because cookies with a safe size are not
       mangled.

       As long as your cookie names don't start with the substring "_bigcookie_" you should be OK
       ;-)

       Demangles name, increments the index and remangles.

SUBCLASSING

       This module is designed to be easily subclassed... If you need to split cookies using a
       different criteria then you should look into that.
