Hi Chris

Thanks for your replies.  I am somewhat new to Tomcat, only been using it for 1 year, so some
of the technical details are new to me.

I will need to check URL-based session ids.  How do I check?  Also, my browser does not have
cookies disabled.

> Is the browser or the server (or both) on Windows 2012?

The server is on Win 2012.  It works OK when both the browser and server are the same 2012
VM.  I don't know if it works when both client and server are both Win 2012 but different
machines.  I will be able to check that soon.  It does not work with different client OS version
and box than the server, but that may simply be coincidence.

Wow, that sounds intimidating - never done that before.  :-)

After re-reading your post, it's pretty clear that my initial questions will be worthless
and not help you.

Is it possible that you are not using URL-based session ids, and that your browser has cookies
disabled via a policy? Is the browser or the server (or both) on Windows 2012?

Try using a protocol sniffer to see if the browser is sending a session id to the server,
and if the server is responding with a session id either before or after login.
