A PAC file is a JavaScript file that defines a FindProxyForURL function, which tells the browser to either redirect to a proxy server or connect directly to the URL. Introduction. Since 2007 FindProxyForURL.com has been the go-to resource for practical assistance with creating and deploying PAC files.. This website is the result of a decade of experience assisting companies small and large in deploying PAC files and WPAD with a cloud security service. Using variables within a PAC file can be an extremely powerful way to simplify your PAC file. You can create variables to hold almost any value - A client's IP address, a proxy server address, a true/false value, etc. This variable can be read and reset at any point in the PAC file. To use a variable, all you need to do is set it to a value.

A Proxy Auto-Configuration (PAC) file is a JavaScript function definition that determines whether web browser requests (HTTP, HTTPS, and FTP) go direct to the destination or are forwarded to a web proxy server.
The main difference between PAC file and setting for proxy server: - proxyserver: one proxy server address and port and maybe some exceptions for direct access to webservers: valid in simple environments - PAC file: file containing a javascript function named FindProxyForURL(url, host), which is called automatically by the browser for every
WinHttpDetectAutoProxyConfigUrl function (winhttp.h
Note: If PAC files are pushed by GPO, then that can cause connectivity issues for users of the VPN. Consider this scenario: The PAC file is an Internal URL, not resolvable externally. When IE is opened without being connected to the VPN, the PAC file fails to be found, and thus no Proxy settings are applied, thus there are no issues.
