I was about to scold you for not using Search but I only received two results for "upload file"?! .

The documentation for CGI.pm has a few examples or you can look at this node for an example.

I would definetly recommend using the CGI module as opposed to rolling your own unless it's for learning purposes.

Update

Minutes later, the site went down and I was greeted by the visage of the node reaper, maybe that's why the weak search results.
