Chapter 7: Managing Gopher and WWW Services
If you are using the authenticating HTTP proxy, users must use a proxy-aware browser.
It must support persistent connections if you wish to use strong authentication. Once
you have configured their web browser, they are aware of the proxy because they must
authenticate to access outside sites.
Using Proxy-Aware Browsers
Many Web browsers, such as Netscape and Mosaic are aware of application proxies for
different types of Web services. Once you configure these browsers, the browser sends
the request to the appropriate proxy.
If you are using the authenticating HTTP proxy, ensure that the browser supports proxy
authentication and persistent connections.
Configuring Web Browsers
The steps vary depending upon the browser, operating system, and version. Some
browsers allow you to indicate the information using a dialog box from a preferences
menu, while others require you to edit a configuration file, and others use environment
variables.
If you are using the authenticating HTTP proxy, ensure that the browser supports proxy
authentication and persistent connections.
To configure the browser, follow these steps:
1. Specify that you can only have one network connection at a time if you are using the
authenticating HTTP proxy with strong authentication.
2. Specify the name of the firewall for the HTTP proxy and port 8080 as the HTTP port.
3. Specify the name of the firewall for the Gopher proxy and port 8080 as the Gopher
port.
4. Specify the name of the firewall for the FTP proxy and port 8080 as the FTP port.
Note that this is not the standard FTP port 23. When the firewall receives an FTP
request on port 8080, the http-gw proxy does the actual FTP processing, not the
ftp-gw proxy. This is because Web browsers use the HTTP protocol to communicate
with the firewall proxy, not the FTP protocol.
5. Specify the name of the firewall for the security proxy and port 8080 as the security
port.
