How do I stop my IIS App Pool making a request to wpad.mydomain.com?
- by Programming Hero
As part of some performance troubleshooting, I've monitored the slow startup of a "cold" App Pool (one without an active worker process) in IIS.
When using a built-in account, the App Pool starts in sub-second time. When using a custom local account the App Pool takes 30+ seconds to start processing requests.
The service appears to be making requests to wpad.mydomain.com, an address it does not have access to, which causes it to wait 30 seconds for a response before eventually timing out. As a workaround, I've added the hostname to the server's hosts file, to direct the traffic to the local machine, which returns much faster (1-2 seconds).
What do I need to do to stop IIS making this request when this identity is used for the App Pool?
