I've got a multiple step webform written in c#/asp.net. I'm trying to change the url that posts back to for google analytics reasons. I've written the code below to change the url on the client side, but it doesn't seem to post to the url with the parameters on the end. Almost like it's being changed back on the client side onsubmit. Any ideas?
