Sample PAC File
A proxy auto-configuration (PAC) file is a text file that instructs your system to forward traffic to a proxy
server.
The following code shows a sample PAC file.
function FindProxyForURL(url, host)
{
if ( url.substring (0, 5) == "http:" )
{return "PROXY 10.221.77.3:8080; PROXY 10.221.76.7:8080;DIRECT";}
else if ( url.substring (0, 6) == "https:" )
{return "PROXY 10.221.77.3:8080; PROXY 10.221.76.7:8080;DIRECT";}
else
{return "DIRECT";}
}
The Function “
function FindProxyForURL(url, host)
” returns a string with one or more access
method specifications. These specifications cause your system to use a particular proxy server or connect
directly.
This function instructs your system to retrieve information for http / https protocols using the first proxy,
that is “PROXY 10.221.77.3:8080”.
If “PROXY 10.221.77.3:8080” is unreachable/unresponsive, then your system tries the second proxy, that
is “PROXY 10.221.76.7:8080”.
