If anyone can help me with this it will save me from pulling out the rest of the hair on my head!

We have some PDF documents that we only want registered users to be able to download. So I've built a new page (aka Resource Page) that accepts URL parameters for document type and the document name. If the user is logged in it opens the document dynamically in an iframe. That works perfectly.

If the user is not logged in then I redirect them to the Login page with my Resource Page as the returnurl. So my login page URL looks something like this... http://192.168.10.183/ssctechdev/Defa... 

This works great unless the user needs to register. If the user gets directed to the Login page and then clicks Register the returnurl is passed to the Register page, but then it doesn't work because it is a relative path. I end up getting this...

http://192.168.10.183/ssctechdev/Soft...

Now - here is where I am stuck. If I use a fully qualified URL as the returnurl then neither the login nor the register page works. It ends up going back to the original page that the user came from. (Note the tab ID in in the URL is dynamically generated based on the page they came from. See the links to these resources could be anywhere on our site)

Any ideas on how to get the fully qualified URL to work? This is what the URL looks like when it is set to the fully qualified one.

Thanks in advance for any help.
