Sample PAC File Usage

The following examples show the URLs listed in the Proxies for Domains and Subdomains list and the corresponding PAC file.

Example with Either DIRECT or NULL Return

If these proxies are used for domains and subdomains:

*intranet1.com proxy.intranet.com:8080

intranet2.com proxy.intranet1.com:8080

the corresponding PAC file is:

// Start of the PAC File
function FindProxyForURL(url, host) {
         if (dnsDomainIs(host, ".intranet1.com")) {
             return "DIRECT";
         }
          if (dnsDomainIs(host, ".intranet2.com")) {
              return "PROXY proxy.intranet1.com:8080";
          }
          return "NULL";
}
//End of the PAC File

Example with STARPROXY Return

If these proxies are used for domains and subdomains:

intranet1.com

intranet2.com.proxy.intranet1.com:8080

internetproxy.intranet1.com:80

the corresponding PAC file is:

// Start of the PAC File
function FindProxyForURL(url, host) {
          if (dnsDomainIs(host, ".intranet1.com")) {
              return "DIRECT";
          }
          if (dnsDomainIs(host, ".intranet2.com")) {
              return "PROXY proxy.intranet1.com:8080;" +
                  "PROXY proxy1.intranet1.com:8080";
          }
          return "STARPROXY internetproxy.intranet1.com:80";
}
//End of the PAC File

In this case, if the request is for a host in .intranet2.com domain, the Gateway contacts proxy.intranet1.com:8080. If proxy.intranet1.com:8080 is down, the request fails. The Gateway does not failover and contacts proxy1.intranet1.com:8080.
