Hi all,

This is my first post here...

I'm writing a web interface using CGI::Application for a project that houses numerous methods within a dozen modules.

One particular process displays a template to the user with passed in data, and then has four more steps before completing. The result of this procedure will be the modification of an elaborate data structure. The data structure may need to be modified along the way.

Given that I can get through the web GUI portion of the process with just a couple of params, I'd like to find a way to retain the entire data structure without having to re-instantiate it (which requires rebuilding numerous objects etc), or pass each variable within it as a param on each CGI invocation.

Can I, and is it plausible to create a cyclic ref redundancy of the data structure, store the memory location in a variable, pass the variable data as a param, and then recreate the data based on the variable that contains the memory location at the end of the entire CGI process? Is exploiting Perl's garbage collection like this possible, and ok to do?

I'd like to be able to 'carry' the data structure without having to 'store' it to disk, if possible

Steve
