NAME

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

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

       split @cookies
           This method accepts a list of CGI::Cookie objects (or look alikes) 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 @cookies
           This is the inverse of "split".

       should_split $cookie
           Whether or not the cookie should be split

       mangle_name_next $name
           Demangles name, increments the index and remangles.

       mangle_name $name, $index
       demangle_name $mangled_name
           These methods encapsulate a name mangling scheme for changing the cookie names to allo
           wa 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 ;-)

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.
