(Windows) Using an External Web Server for Multiple
Stand-Alone Instances of PPM
Because of Windows registry limitations, you cannot use just one Web server for multiple stand-alone PPM instances on a machine running Windows. Integration with an external Web server involves specifying the worker_file registry directive that points to the
workers.properties file. The
workers.properties file tells the redirector (
isapi_redirect.dll) where to forward the request. Redirecting to two different instances does not work because each instance requires different workers properties. However, a single Windows registry points to only one
If you must use an external Web server for multiple stand-alone PPM Server instances, we recommend that you either use a UNIX machine to host the Web server, or use a hardware load balancer.
