Question

Determine target URL within login page using Forms authentication with WebLogic

Answer 1

A:

It's stored as request attribute with the name javax.servlet.forward.request_uri.

Thus, you can access it by either EL in login JSP:

${requestScope['javax.servlet.forward.request_uri']}

or by raw Java code in either servlet or filter associated with login JSP, or in (cough) scriptlet:

request.getAttribute("javax.servlet.forward.request_uri");

Thanks BalusC, but this attribute does not exist. In fact, request.getAttributeNames() returns an empty list. Perhaps the login page works differently from standard forwarding?

Maybe weblogic uses an proprietary approach. Or you tested it the wrong way. You shouldn't open up the login page directly. By the way, Weblogic should not have literally **redirected** the request to the login page, but instead just **forwarded** the request to it. A redirect namely creates a brand new request, hereby losing all original attributes.

Answer 2

A:

We concluded there was no way to find out the target URL from the login page. I woudln't mind being proven wrong. :)

In the meantime, the solution was to deploy the content in second WAR with it's own login page providing the alternate content. Lots of overhead for what should be a simple problem to solve.
