What do you mean by "invoke"? Do you include the other JSP or do you 
issue a redirect?

If you do a redirect, then you are on a different page and you would 
have to inspect the "referrer" HTTP header, which might not necessarily 
be sent by the client or have to keep some session state, etc..

If you just include another JSP into your template, then the call of

   cms.info("opencms.url");

will return the URL of the overall page and you should not have a problem
