PAC
A Proxy Auto-Configuration file (PAC file) is a file which contains a function, FindProxyForURL()
, which is used by the browser to determine whether requests (including HTTP, HTTPS, and FTP) should go directly to the destination or if they need to be forwarded through a web proxy server.
js
function FindProxyForURL(url, host) {
// …
}
ret = FindProxyForURL(url, host);
See Proxy Auto-Configuration (PAC) file for details about how these are used and how to create new ones.
