cgi::cookie::splitter
CGI::Cookie::Splitter(3pm) User Contributed Perl Documentation CGI::Cookie::Splitter(3pm)
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.
