Duplicate requests with Apache and WebLogic

When you run Apache in combination with WebLogic, you observe duplicate requests in CQ, especially for long-running requests. For example, there are duplicate requests when you are re-creating a large package (2 MB or more).

The following setup is potentially affected:

• using Apache to proxy requests to CQ
• mod_weblogic
• WeblogicCluster setting enabled in mod_weblogic
  

Try one of the following:

• Reconfigure Apache to have a longer timeout to allow long running requests to complete.
• Disable this feature.
  

This issue occurs when Apache's fail-over mechanism triggers Apache to reissue an additional request to the application server once a preset timeout is reached.
