RE: Tomcat 4 losing session (may be related to Win XP)
The one that doesn't work is behind a proxy server doing proxypassdir's to map a URL to an internal IP. Could this be the problem, or is it an IIS thing? I am pretty sure the proxy is the problem. The proxy server is serving the cached pages for page1, but then when you need to do a GET for page2, a new session was created on tomcat server because the first session created was not on tomcat server.

RE: Tomcat 4 losing session (may be related to Win XP)
I do not get the same value back, and our app does not use jsessionid currently. If I install the pages on a server that works properly, I get the same value back between page views. On this server, I get different values, which is consistent with losing session. There is no proxy in the way (all intranet) (that I know of; I'm not a network engineer but I play one at work, and so I believe that the parallel discussion about proxy servers does not pertain to my issue) (possible that WinXP installs some sort of proxy server software like internet connection sharing or something like that??) To add weirdness to the issue, yesterday, the little two page app worked properly if installed in the Tomcat examples directory on the misbehaving server; today it does not. I had modified the server.xml file, and tried to change it back (from memory; I didn't make a big change) but failed to resolve the problem. I will do yet another clean install and trace my steps carefully. Thanks for everyone's help.

RE: Tomcat 4 losing session (may be related to Win XP)
I don't think it's a question of cached pages, but proxyserver does seem to be doing something. The first page is a login, and when it's submitted, the request passes a query string that calls the servlet. Servlet creates a new session and I can see a new cookie containing JSESSIONID. The servlet then displays results from a db query. Any further requests, whether to scroll the results, add new record, or view individual record causes the servlet to create a new session because request.getSession(true) is called and doesn't find the cookie in the request. Accessing the web app from inside the proxy works okay. -Original Message- From: Yansheng Lin [mailto:[EMAIL PROTECTED] Sent: Thursday, November 06, 2003 11:48 AM To: 'Tomcat Users List' Subject: RE: Tomcat 4 losing session (may be related to Win XP) The one that doesn't work is behind a proxy server doing proxypassdir's to map a URL to an internal IP.

I've been pulling hair out for several days with what turns out to be the same problem, except it's occurring on a Windows 2000 Server running IIS 5.0 and Tomcat 4.1.24. The logs show that the first request to a servlet done via POST gets a different session id than the follow-on request via GET to the same servlet, same URL. The same app works fine on another Win2K server running Apache. The one that doesn't work is behind a proxy server doing proxypassdir's to map a URL to an internal IP. Could this be the problem, or is it an IIS thing?

The logs show that the first request to a servlet done via POST gets a different session id than the follow-on request via GET to the same servlet, same URL. The same app works fine on another Win2K server running Apache. The one that doesn't work is behind a proxy server doing proxypassdir's to map a URL to an internal IP. Could this be the problem, or is it an IIS thing? If you really want to see what's happening, put your own proxy between the client and the first server on your backend (I use zproxy -- google for it) to look at the http messages going back and forth. Check the response that you're getting from Tomcat and note the JSESSIONID provided after the first call. See what JSESSIONID the client machine sends back. You can put the same proxy (or any http-level sniffer) between any of the servers and see who's passing what. If you've established that Tomcat is receiving two different sessionId values, then you can be sure there's a mixup somewhere else (and the more hands you've got in the cookie jar, the more chances someone else is screwing things up).
