Disable sessions
Hello,
I've been struggling with the 1.1-rc1 release since I didn't seem to be
able to disable sessions in Struts. I've read through the mailinglist
and tried several solutions. I also noted the responses that shortly
say 'Struts doesn't handle sessions, your servlet container does'. Well
I have the impression that Struts does manage them.
I've briefly read through the sources and there are several locations
where Struts clearly starts a new session. I haven't investigated in
detail though. Maybe someone else can enlighten me?
For that purpose I've tried the shortest possible testcase and even
removed a JSP view. Still, Struts tries to start a session.
Below are all the related files. Does anyone have an idea what I can do
to completely disable sessions?
Thanks for the help,
Geert Bevin

Re: Disable sessions
Posted by Ted Husted <hu...@apache.org>.
Struts was *not* designed with the idea of obviating use of the session
in mind. It's quite possible that there are places where an effect of
some operation may ask the container about a session.
The source code is available for your perusual. If there were some
simple patches to the controller that could be applied, they could be
considered for post 1.1. Please see Bugzilla for any submissions.
The custom tags have URL encoding built in, which relies on the concept
of a session, and that's not going to change. If you intend to use the
custom tags with Struts but must be totally session free, then my best
suggestion is to look at some of the other frameworks. But I don't know
if any of those will meet your requirements either. Google lists several
