Hi, We have installed our reporting solution on weblogic and proxy the weblogic from Apache using weblogic proxy pluggin. For some users we have made the apps available by proxying Apache from IIS (we have installed the weblogic proxy plugin on IIS and point it to Apache ). Normal URL's are accessing fine. But in our reporting solution there is an option to export the report which send us 404 error in accessing this way. On further investigating the issue we found that accessing the apps in this manner, on hitting Export option request is not going to weblogic also. Apache throws the 404! (Error logs shows that JVMID is stale) To remove the error possibility areas we have removed the apache and access the Weblogic directly using IIS and export option is working fine. Also directly accessing the apps using apache is also working fine. Seems something wrong between IIS and APache which we are not able to trace . Could any one please tell me where can be the issue. Below are the pluggin settings on IIS and Apache IIS:- WebLogicHost=<host name> WebLogicPort=8080 ConnectionTimeoutSecs=20 ConnectionRetrySecs=2 WlForwardPath=/ DebugConfigInfo=OFF Debug=ON idempotent=OFF WLSocketTimeoutSecs=2 WLCrossOverProxyEnabled=ON WLLogFile=C:\\temp\\wllog.log Apache: WebLogicCluster <cluster name> idempotent OFF WLSocketTimeoutSecs 2 WLCrossOverProxyEnabled ON DebugConfigInfo OFF Debug ALL WLLogFile /opt/iam/Apache32/logs/Wl_Proxy_OBIR.log
