I have Spring app that uses JSP. And I need to redirect one page, but only once. It's due the spring security - once the user comes to this page, I need to call redirection to log him out, but to stay on the same page. Is there any way, how to do this only via java, html or js? Or maybe I've asked wrong - there must be some way, how to do this, but I'm not very into frontend technologies, so I'd be glad, if anybody could post some code to show me, how to make this work.. Thanks 
So the usecase: user types mywebsite.com/login -> I need to call redirect to log him out in the case he's already logged -> the same site shall appear but now without redirection.PS: I can't redirect the user to another site - it must be the same site with same source code.
