Open Google Chrome, open the Chrome menu, then click Settings. Click Show advanced settings. Go to Network and click Change proxy settings. Click LAN settings. A PAC file can: Be stored on any server in your network. Small networks may store the file on the proxy itself, but large, enterprise-class networks should use a separate server for storing the PAC file. About PAC File. A proxy auto-configuration PAC file is a text file that instructs a browser to forward traffic to a proxy server, instead of directly to the destination server.

PAC files can be hosted on a workstation, on an internal web server, or on a server outside the corporate network. Click on Start and then click on the gear icon Settings at the far left. In the left-hand pane, click on Proxy at the very bottom. Here you have all the settings that are related to setting up a proxy in Windows.

If you have multiple proxy servers, click Advanced to look at all of the additional addresses. Select Internet Options from the results list. Click to open the Connections tab. Click the LAN settings button. Notice in the Proxy Server section:. Select Settings. In the "Network" section, click Change proxy settings.

Open the edited PAC file in a text editor such as Notepad. Edit the file as appropriate for your deployment. Upload the edited PAC file to your internal web server and note the path to the file. A proxy server is a computer system or router that functions as a relay between client and server.

If left unspecified, times are taken to be in the local timezone. If only a single value is specified from each category: day, month, year , the function returns a true value only on days that match that specification. If both values are specified, the result is true between those times, including bounds, but the bounds are ordered.

Note: Before Firefox 49 the category hour1, min1, sec1 must be less than the category hour2, min2, sec2 if you want the function to evaluate these parameters as a range. If only a single value is specified from each category: hour, minute, second , the function returns a true value only at times that match that specification.

Warning: The order of the hour, minute, second matter ; Before Firefox 49, timeRange 0, 23 will always evaluate to true. Now timeRange 23, 0 will only evaluate true if the current hour is or midnight.

Note: Since all of the examples that follow are very specific, they have not been tested. All hosts which aren't fully qualified, or the ones that are in local domain, will be connected to directly. Everything else will go through w3proxy. If the proxy goes down, connections become direct automatically:. Note: This is the simplest and most efficient autoconfig file for cases where there's only one proxy. If there are hosts such as the main Web server that belong to the local domain but are outside the firewall and are only reachable through the proxy server, those exceptions can be handled using the localHostOrDomainIs function:.

The above example will use the proxy for everything except local hosts in the mozilla. Be careful to note the parentheses around the or expression before the and expression to achieve the above-mentioned efficient behavior.

This example will work in an environment where the internal DNS server is set up so that it can only resolve internal host names, and the goal is to use a proxy only for hosts that aren't resolvable:.

The above requires consulting the DNS every time; it can be grouped intelligently with other rules so that DNS is consulted only if other rules do not yield a result:. In this example all of the hosts in a given subnet are connected-to directly, others are connected through the proxy:. Again, use of the DNS server in the above can be minimized by adding redundant rules in the beginning:. This example is more sophisticated. There are four 4 proxy servers; one of them is a hot stand-by for all of the other ones, so if any of the remaining three goes down the fourth one will take over.

Furthermore, the three remaining proxy servers share the load based on URL patterns, which makes their caching more effective there is only one copy of any document on the three servers - as opposed to one copy on each of them. The load is distributed like this:. All local accesses are desired to be direct. All proxy servers run on the port they don't need to, you can just change your port but remember to modify your configuations on both side.

As an example, to set different proxies based on the protocol the startsWith function can be used:. Note: The same can be accomplished using the shExpMatch function described earlier.

Note: The autoconfig file can be output by a CGI script. Usage of isInNet , isResolvable and dnsResolve functions should be carefully considered, as they require the DNS server to be consulted. All the other autoconfig-related functions are mere string-matching functions that don't require the use of a DNS server.
