Return link at logout
High level discussion
When sending the user to the CAS logout page, you might want to provide a URL to CAS such that when it paints the logout page it provides users an opportunity to follow a link to someplace interesting. For instance, upon logging out of CAS from your uPortal instance, you might have the CAS logout screen provide a link back from CAS logout to the uPortal guest page.
Implementation notes
Implemented by Yale as checking for the request parameter "url" in the logout.jsp display logic, displaying a link to the provided URL if the parameter is present.
