Hi everybody,
Working on my company webapp I notice the following problem: sometimes the
jsession cookie is lost, and therefore my whole http session is lost.
The context is:
- Tomcat v. 5.5.36
- JDK 1.5.0
- O.S. Windows
- Client: Internet Explorer 8
Here is my use case:
- I made a POST request to a servlet of my webapp
- While processing this request, I create a new http session
- Processing of the request will process a velocity template as
last step
- This velocity template contains 3 calls to 3 different servlets
of my webapp, these 3 calls are made through an HTTP GET
- While processing one of these 3 requests, Tomcat does not append
jsessionid parameter to the requested URL: I have debugged Tomcat classes
therefore I am sure of this
This problem does not occur always, but just sometimes. While debugging
Tomcat classes, I noticed that Tomcat starts 3 threads to manage the 3 GET
requests of the velocity template, so maybe it is a concurrency problem.
Finally, I noticed that this problem does not happen if I set the Windows
registry key HKCU\Software\Microsoft\Internet Explorer\Main – TabProcGrowth
to 0 or 1, which forces Internet Explorer to use one process for all tabs,
not one process for single tab (which is the default).
Do I miss some configuration settings? Do I have to set some particular
parameter / cookie in the first response (or in the velocity template) ?
If you need more details please tell me.
I have sent this question to the dev list since I don’t know if this is a
Tomcat bug, but if you tell me this is the wrong list I will unsubscribe
and post this question to the user list.
Thanks in advice,
Kind regards
Diego
