I am running Tomcat 5.0.28, mod_jk 1.2.8, and Apache/2.0.46 on Redhat Enterprise Linux WS 3.0.

We have an HTML page that is a frame: top (banner), left hand (menu), and right hand (main content). There are 6 hyperlinks in the LH pane that point to *.jsp pages that load in the RH pane via a
<BASE TARGET="displayContents"> tag. Usually, these links work. But occasionally when clicking one link, content that belongs to another link appears in the main/RH pane. This problem seems to get worse the longer Tomcat is up.


The JSPs that we are using don't make use of sessions as far as I can tell. Logins are not required. The JSPs are only used to generate dynamic content and forms for submission.

I have tried setting the following in workers.properties:
  worker.workerHADS.socket_keepalive=FALSE
  worker.workerHADS.cache_timeout=60
  worker.workerHADS.cachesize=1
  worker.workerHADS.reclycle_timeout=30

I added this within the <head></head> section of each JSP:
  <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
  <META HTTP-EQUIV="Expires" CONTENT="-1">

But the problem still presents occasionally. It happens on Mozilla and IE browsers, and probably others. It looks like a server side issue. It is not 100% reproducible. It cannot be reproduced immediately after Tomcat is started. But after several hours (or possibly some number of visitors to the page) it starts to happen and gets more frequent over time.

Any suggestions would be greatly appreciated!
  Thanks, Brian
