Using the Web proxy server<br />

Caching—The Web proxy server provides support for Web caching<br />

on the <strong>Sidewinder</strong> <strong>G2</strong>. Web caching can improve performance <strong>of</strong> a<br />

user’s Web browser by caching Web documents in the <strong>Sidewinder</strong><br />

<strong>G2</strong> cache memory. When a user accesses a Web site, each new<br />

Web page that the caching server downloads is also saved in cache<br />

memory. The next time the user requests that page, the caching<br />

server retrieves it from the cache rather than downloading it from<br />

the network a second time.<br />

Important: If you use the Web proxy server in non-transparent mode, all Web<br />

browsers on your internal workstations must be configured to point to the<br />

<strong>Sidewinder</strong> <strong>G2</strong> internal name and to whatever port you have configured for the Web<br />

proxy server. For information on what users need to do to configure their Web<br />

browser, see “Configuring browsers for the Web proxy server” on page 12-19.<br />

Setting up Web access using the Web proxy server<br />

The following steps provide an overview <strong>of</strong> the tasks you must do to<br />

set up Web access using the Web proxy server.<br />

1. Configure the appropriate proxy rules to restrict Web access.<br />

Once you enable the Web proxy server, you must configure one or<br />

more proxy rules to control the burbs from which users can browse, and<br />

to which burbs they can connect. See Chapter 7 for detailed<br />

information on setting up proxy rules.<br />

Note: When configuring the proxy rule for a Web proxy server connection, be sure to<br />

specify Server in the Service Type field.<br />

2. Configure and enable the Web proxy server. See “Configuring the Web<br />

proxy server” on page 12-12.<br />

3. [Optional] Configure authentication Web users.<br />

You can configure the <strong>Sidewinder</strong> <strong>G2</strong> to authenticate all users<br />

requesting Web service using either a basic UNIX password or stronger<br />

authentication methods before the <strong>Sidewinder</strong> <strong>G2</strong> makes the network<br />

connection. Refer to “Configuring authentication services” on page 9-11<br />

for details on the authentication methods supported by the <strong>Sidewinder</strong><br />

<strong>G2</strong>.<br />

4. Inform users how to configure their Web browsers. See “Configuring<br />

browsers for the Web proxy server” on page 12-19.<br />
