I haven't had a large amount of experience with Super Cache, but I do 
have a bit.

To my knowledge, you can't have any server-side processing occur with 
Super Cache since it merely provides static files. Since these are 
static files, the entire WordPress code stack is bypassed and no code at 
all is executed.

The way to introduce dynamic elements with Super Cache is with 
client-side scripting. To quote the FAQ:

    "Other dynamic elements on a page may not update unless they are
    written in Javascript, Flash, Java or another client side browser
    language. The plugin really produces static html pages. No PHP is
    executed when those pages are served."
