Server side? I hope so...
Well you start by using CGI::Cookie, which is whgat cGI.pm uses itself.
There in the "synopsis" in the docs you can see:
# fetch existing cookies
%cookies = fetch CGI::Cookie;
So it's easy enough:
@plug =grep /^PLUG\d+$/, keys %cookies;
gives you the list of all existing cookies of the required format. The
values in the hash are the actual cookie objects.
BTW don't overdo it. People generally don't like it if a site stores
more than 2 or 3 cookies on your browser. Use another mechanism, thus
session-management, if you want to store a lot of data. See for example
CGI::kSession for a small and simple module.
