Search the Internet for tools and strategies available for your organization's chosen browser. In addition to controlling which browsers are allowed and managing their configuration, it is essential that proper firewall policy is in place. No traffic should be allowed to go direct to the Internet, bypassing the proxy, unless it is explicitly allowed by policy. Right click the top-level domain or Organizational Unit where the policy should be applied, select Properties , and then select the Group Policy tab.

Select Enable Automatic Configuration. Under Auto-proxy URL. JVS, or. It will look something like this:. In Automatically configure every field , specify how often the web browser should query for the auto-configuration. For example, if you enter minutes, every 4 hours the web browser checks for an updated PAC file.

If you leave this field blank or set it to "0" the web browser is only configured when it is started. Web clients using Internet Explorer pick up the settings in this GPO the next time that group policy refreshes, which by default is every 90 minutes for clients, and every 5 minutes for Domain Controllers or the next time a user logs off and on again.

You can change the refresh interval in the default domain policy, or by going to a particular client and entering the following at the command prompt:. Also note that if the GPO is not applying the settings to the browser, then it is possible that another GPO is being applied that contains different settings; raising the link order for the new GPO should resolve the problem. However, versions of Internet Explorer since 5.

Because the Automatic Proxy Result Cache is indexed by hostname, it is impossible for a PAC file to distribute traffic to distinct proxy servers based on any part of a URL in addition to the hostname. In other words, it is impossible to direct traffic to different proxy servers based on the path portion of URLs on a single host. This feature is discussed in more detail in the Microsoft knowledge base article titled How to disable automatic proxy caching in Internet Explorer.

Such entries are often referred to as exceptions. Most PAC files already have 1 or more exceptions. Mail will not be published required. Spam is a pain, I am sorry to have to do this to you, but can you answer the question below?

All the other autoconfig-related functions are mere string-matching functions that don't require the use of a DNS server. Most of the time these functions are not necessary to achieve the desired result. Proxy auto-config was introduced into Netscape Navigator 2. Open-sourcing Netscape eventually lead to Firefox itself. These utilities are found in many other open-source systems including Chromium. Firefox later integrated the file into ProxyAutoConfig. To extract it into its own file, it suffices to copy the chunk into JavaScript with a console.

Microsoft in general made its own implementation. There used to be some problems with their libraries , but most are resolved by now. They have defined some new "Ex" suffixed functions around the address handling parts to support IPv6. The feature is supported by Chromium, but not yet by Firefox bugzilla PROXY w3proxy. The auto-config file should be saved to a file with a.

The examples at the end of this document are complete. There is no additional syntax needed to save it into a file and use it. The PAC file is named proxy.
