This article provides relevant information that relates to WPAD (Web Proxy Auto-Discovery Protocol) and its operation.
GFI WebMonitor all versions (Standalone Proxy Version).
WPAD is a convenient way for administrators to configure their client machines to use the GFI WebMonitor server as a proxy server. When this feature is enabled, and the workstation’s Microsoft Internet Explorer Connection settings are configured to 'Automatically Detect Settings,' each client machine will automatically determine the IP address of the GFI WebMonitor server and use it as a proxy without further configuration.
For more information, refer to Configuring WPAD and Troubleshooting Web Proxy Auto-Discovery (WPAD) Issues.
