Remarks

When the HttpWebRequest object is run, it may need to run the WPAD (Web Proxy Automatic Detection) protocol to detect whether a proxy is required for reaching the destination URL. During this process, the system downloads and compiles the PAC (Proxy Auto-Configuration) script in memory and tries to execute the FindProxyForURL function as per the PAC specification.

When doing so, the system creates an internal application ___domain inside the application which runs with minimal permissions, and, most importantly, it does not grant the UI permission to this new application ___domain. The evaluation of a proxy and running the FindProxyForURL javascript function happens in the context of this new application ___domain and during this process the system may need to run several helper functions as per the PAC specification.
