Is it possible to use Prosper with a multi-step landing page? Basically, the user will land on my landing page (go figure, lol). They will then click and go to a secondary page where they will either need to click again or they'll be automatically redirect after a delay.

Can prosper still pass the unique sub-ids?

After a delay? As long as the multi-step aka all the pages are on the same domain, it should be fine.

Perfect! I wasn't sure if the js include would take care of passing the variables.

Sure just place the JS on the 1st page.

And then whenever u want them to be redirected out, use the php redirect code on the last page, it could be page 10, as long as on the same domain, once they arrive a cookie is recorded and then u can call it whenever, even on page 100.

But yes, good luck!
