So it appears that Apache is, over time, losing track of user identities? That seems odd since neither mod_jk nor Apache httpd actually do anything but forward the identity information from the browser to Tomcat. Either an HTTP cookie or a URL parameter is used to identify sessions, and both are provided with every request. Do you have unusually long URLs? Unusually long request bodies? I'm just trying to think of why any data would be mixed-up. Does this happen seemingly randomly, or only for certain pages on your site? Certain source IP addresses? We had some users that were getting all messed up before we recognized that they were doing through google's cache which was seriously confusing just about everything. Fortunately, we could see from our server logs that some requests came from the /real/ remote user and others came from google's domain. Otherwise, all I can think of is that you have some bug in your application <shrug>. How are you doing authentication? How about user identification - aside from relying on session data in Tomcat. > We are contemplating two approaches: > 1) moving to proxy_http.

Trying mod_proxy_http will certainly give you more information.

Are you /sure/ that a Tomcat-only setup doesn't exhibit this problem? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmSOi0ACgkQ9CaO5/Lv0PBpiwCdH2pRuaVP7TRl7E6tOqZbkUQM yuUAniM9m8+Mo9aWiu2G8XQcZjXf2W/M =l0Xk -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
