The PowerServer Web APIs can be directly hosted inside of an IIS Application pool and run in the same process as its IIS worker process (w3wp.exe); this is known as in-process hosting. It is different from the out-of-process hosting which runs the PowerServer Web APIs in a process separate from the IIS worker process and forwards the requests made to the IIS reverse proxy to the Kestrel server.
In-process hosting provides improved performance over out-of-process hosting because requests are not proxied over the loopback adapter, a network interface that returns outgoing network traffic back to the same machine.
This guide talks about the in-process hosting. The configuration of IIS reverse proxy server for the out-of-process hosting will be discussed in Using Kestrel with IIS reverse proxy server.
To implement the in-process hosting of the PowerServer Web APIs in IIS, you will need to deploy Web APIs to IIS using the following methods:
-
Deploys Web APIs to the specified IIS website
To deploy to an IIS website on the remote server (e.g. IIS on Windows Server 2019), you will need to set up the server in this way:
To deploy to an IIS website on the local server (e.g. IIS on Windows 11), you will need to set up the server in this way:
-
Deploys Web APIs to a folder, and then manually copy files from the folder to the web root of the IIS website.
This will require you to set up the server in this way:
