  • The proxy server is used to access Web pages by the other computers. When another computer requests a Web page, it is retrieved by the proxy server and then sent to the requesting computer. The net effect of this action is that the remote computer hosting the Web page never comes into direct contact with anything on your home network, other than the proxy server.

    Proxy servers can also make your Internet access work more efficiently. If you access a page on a Web site, it is cached (stored) on the proxy server. This means that the next time you go back to that page, it normally doesn't have to load again from the Web site. Instead it loads instantaneously from the proxy server.

    A proxy server acts as an intermediary between your computer and the Internet. It is most frequently used when there is a corporate intranet and users are connected to a LAN. It can also work with a firewall to provide a security barrier between your internal network and the Internet. In addition, corporate administrators can balance proxy loads and block undesirable sites. Proxy servers are becoming more advanced in their ability to reduce network traffic by caching content that is frequently requested by the browsers they serve.

    A key benefit of Internet Explorer 5 is that users can have multiple connection configurations. Proxy and other LAN settings can be altered for each connection configuration, and a friendly name can be assigned to each configuration - for example, "docking station."

    The following section covers two key issues that you should consider if your organization uses proxy servers:

    Configuring proxy port settings

    Configuring proxy bypass lists

    Proxy Configuration (Corporate Administrators and ISPs)

    Corporate administrators and ISPs can preset proxy server settings by entering the settings in Stage 4 of the Internet Explorer Customization wizard. The following illustration shows the Proxy Settings screen.

    These settings in the Customization wizard correspond to proxy settings in the browser. To see these settings in the browser, click the Tools menu, and then click Internet Options . Click the Connections tab, and then click LAN Settings . To see addresses of specific proxy servers, click Advanced .

    Selecting the Use the same proxy server for all protocols check box in the browser or the Use the same proxy server for all addresses check box in the Customization wizard makes all the other entries unavailable and copies the proxy information in the HTTP setting into the other protocol settings. Selecting the check box also hides the information in the Socks setting.

    The Secure setting is for HTTPS requests based on the Secure Sockets Layer (SSL) technology.

    Proxy locations that do not begin with a protocol (such as http: // or ftp: // ) are assumed to be a CERN-type HTTP proxy. For example, when the user types proxy , it's treated the same as if the user typed http://proxy . For FTP gateways, such as the TIS FTP gateway, the proxy should be listed with the ftp:// in front of the proxy name. For example, an FTP gateway for an FTP proxy would have this format:

    ftp://ftpproxy
    

    When you enter proxy settings, use the following syntax, where <address> is the Web address of the proxy server and <port> is the port number assigned to the proxy server:

    http://<address>:<port>
    

    For example, if the address of the proxy server is proxy.example.microsoft.com and the port number is 80, the setting in the Proxy Server box for LAN settings in the Proxy Settings dialog box or the Proxy Settings screen of the Customization wizard should read as follows:

    http://proxy.example.microsoft.com:80
    

    Note If you are using the Internet Protocol (IP) address of your proxy server, make sure not to type leading zeros. For example, use 130.25.0.1 instead of 130.025.000.001.

    Key proxy registry settings are as follows:

    HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\
    Internet Settings\
    "ProxyEnable"="01 00 00 00"
    "ProxyServer"="data"
    "ProxyOverride"="local"
    

    The proxy bypass list in the Exceptions area of the Proxy Settings dialog box allows users to specify addresses that will bypass the proxy server and be accessed directly.

    Corporate administrators can also preset proxy settings or manage proxy settings by using an automatic proxy configuration file in .js, .jvs, or .pac format. For more information about automatic proxy configuration
