Don't make us guess your problem!!! ---------------------------------------------------------------- We're trying to get load balancing set up between Apache and Tomcat, using mod_jserv. The connection itself seems to work fantastically, and the whole site runs fine, except for one thing: it crunches after a few page loads. When we sniffed the cookie being returned to the user's browser, we found that the ApJServRoute string is not being appended to the JSESSIONID cookie. mod_jserv's load balancing mechanism is supposed to work by appending a few characters (say "JS1" or "JS2") as defined with the ApJServRoute directive to the end of the session id cookie (at least, that's what we understand from Jean-Luc's paper). This allows the next request which comes into an Apache server to be sent to the correct servlet machine, which, among other things, has the user's current session information. Since the "JS1" (or "JS2") isn't being appended, it's no surprise that you eventually hit a different servlet (Tomcat) machine which doesn't know about your session, and down you go. We're at a bit of a loss trying to determine why this isn't happening. Has anyone encountered this? I realize that Jserv is a servlet engine itself, but the mod_jserv funtionality seems to have been merged between the two projects, and there have been brief reports in faq-o-matic and the Tomcat mailing list archive that there has been success with this. [We have four web servers running Apache 1.3.11 in front, and two machines running Tomcat 3.1 in the back; all upon Sun machines running Solaris 2.7. The httpd.conf mods are right out of the Java-Apache project's Load Balancing HOWTO, (and yeah, it's the same httpd.conf on each web server)] I've hunted through the source code, and I can't immediately see anything wrong, so we suspect we're configuring something incorrectly. The Apache directives of our configuration are appended.
