More generally, Tomcat, or any other web server, has no clue what a
"frame"  is.  All it does is respond to requests that come in, and the
requests for each frame are (from the perspective of the server) all
separate.

There is no other way. There is no way for Tomcat to know "in which frame the client 
is". It is up to the browser to play with displaying of HTML and frames. And the only 
way to do something on the client side is to use J(ava)Script.

Nix.

Thanks Craig,

That is perfect.  I was hoping to avoid JavaScript, but I couldn't find any
other way.

Thanks again!

We ran into this exact issue with the admin webapp in Tomcat 4.1.x (which
also uses frames), and solved it by adding the following to the top of the
login page:

  

  

This causes the login page to immediately redisplay itself if it gets
shown inside a frame.

Hi,

I have a webapp that uses Tomcat login security and html frames.  If a
user's session times out, and the user tries to access the webapp Tomcat
calls the login page as expected.

The problem is that the old frame is still in the browser and the login page
appears in whichever frame was last active, with all of the other frame junk
still on the page.

Is there a way to get Tomcat to call the login page with a target of _top so
it clears the old frames out of the browser?

Thanks,

Rick
