Additional URL in a URI?

[eluser]Iverson[/eluser]
I need to do something similar to the way Digg captures a url and sends it to their site. For example, when a user clicks on

Code:

http://www.example.com/getlink/http://www.anothersite.com

I want to grab that url and use it on the page. I don't want to use query strings and I keep getting an error from xajax...

Unable to parse URL
Filename:libraries/xajax.php
Line Number: 1641

Is there anyway to do this with just my models and controllers?
