Subject Re: [Authentication] - User with mixed Sessions
Date Thu, 05 Dec 2002 09:29:41 GMT
Christoph:

Many thanks for the help you provided. Today I will confirm if the problem
was related to the problem in the "multithreading" of Cocoon or if I have
a bug into my code.

If everything is fine I will try to turn on the proxy again to improve the
performance. Since there are no more than 40 users. I think this is not
urgent to turn the proxy on. But I think we need to know if Cocoon will
work or not with the proxy turned on.

As long as I reserched, the cookies must be enough to keep the track of
the users' sessions. On the page 303 of the book "Cocoon: Building XML
Applications" states:

"The default is usually to use cookies because the developer of the web
application does not need to do anything special to use them...."

To assure the authentication is the only one that creates sessions and I
am using also the XSP Session LogicSheet. I was also explicitly turned off
the generation of new sessions in my XSP pages with:

xmlns:xsp-session="http://apache.org/xsp/session/2.0" create-session="false">

Best regards,

Antonio Gallardo.
