CGI::Cookie::Splitter - Split big cookies into smaller ones.
my $splitter = CGI::Cookie::Splitter->new(
size => 123, # defaults to 4096
@small_cookies = $splitter->split( @big_cookies );
@big_cookies = $splitter->join( @small_cookies );
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.
$splitter = CGI::Cookie::Splitter->new(%params)
The only supported parameters right now are "size". It defaults to
@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.
$cookie = $splitter->join(@cookies)
This is the inverse of "split".
Whether or not the cookie should be split
These methods encapsulate a name mangling scheme for changing the cookie names
to allow a 1:n relationship.
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.
This module is designed to be easily subclassed... If you need to split cookies
using a different criteria then you should look into that.
