Not so sure it can be done, not if I understand you correctly.

No webserver is going to execute code that is sent by a browser, they are not really in the business of two-way communication.

You are going to need server access. Now, if you do have that, you'll be able to write whatever you want on the server end -- some kind of program to return the results you're looking for. But, as far as the browser submiting perl code for execution, I don't think that's such a good idea.
