TeamConnect 5.2 only supports IIS Web Server 8.
For the Apache web server, it may be necessary to change a default timeout setting to prevent the server from resubmitting a HTTP request when the original request does not return for a long time. The setting, WLIOTimeoutSecs, has a default value of 300 seconds. Shown below is an example for the WebLogic plug-in module, from file weblogc.conf file in the %APACHE_HOME%/conf folder:
<Location /Filenet_Demo>
SetHandler weblogic-handler
WebLogicPort 4050
WLIOTimeoutSecs 300
</Location>
You should be able to configure this setting in other web server plug-ins, too.
If your requests may take longer than 300 seconds to execute, increase the value from 300 to a more appropriate value.
