This policy is deprecated and is only respected by View 4.x clients and earlier. View 5.0 clients and later automatically use a proxy.pac file if Windows is configured to use it.
A proxy.pac file defines how web browsers and other user agents can automatically choose the appropriate proxy server for fetching a given URL. If proxy.pac file is used on a multi-core machine, on some rare occasions, WININET used by VMware View Client 4.x and earlier to find the proxy server information might crash. If WININET crashes on your machine, do not use this property. This property is disabled by default.
