Passing Query_String or variables through multiple pages?

Hi all, I have an issue I'm hoping there's a simple answer for (I'm betting there is): I have a dynamic page where the user may click on a link - this link processes their data and shows them a "result" page... Then I want a variable (for a manual hypertext link) that contains the original URL they were viewing. The problem is, the original page / URL needs a query string (i.e. "?key1=val1&key2=val2&key3=val3..."). So I have to somehow pass their original query string THROUGH the "result page" via a GET, and without using a <form> (using a POST form I could do it)... I've looked at manually copying and "forwarding" each original variable by including it in the URL for the "result page"; but I was hoping for something more elegant and flexible... Any thoughts or ideas? Thanks a bunch in advance! Take care, --Noel
