Webcache as a proxy server. This applies to both Internet Explorer and Netscape browsers.

If you do configure the Web browser in this way, you may encounter unexpected behavior when a disconnection occurs between the browser and the Webcache. Examples of a disconnection include:

■ Rebooting the Webcache.

■ Changing the Webcache system time

configuration.

In these scenarios, it is possible for Web interface screens to remain open even after the operation has completed successfully. The failure of these screens to close does not cause any problems to the Webcache. Simply refresh the Web browser and the Webcache will operate as normal.

These issues will not occur in Netscape if you select Edit > Preferences > Advanced > Proxy and then select the Direct Connection To the Internet option.

■ Do not try to administer two Webcaches using the

Web interface from the same client machine at the same time. If you do, the web management sessions may interfere with each other and cause unexpected behavior.

■ If you use a Web browser to access FTP sites, there

are a very small number of sites that will refuse access due to an authentication failure, even though they claim to allow anonymous access. This authentication failure is a problem in the SuperStack 3 Webcache software and affects Webcache deployments in both proxy and transparent mode.

If you encounter this problem, you can regain access to the FTP site by using an FTP utility rather than by accessing the site through the Web browser. This will allow you to download the files as expected.

3Com Network Supervisor

The CD-ROM contains 3Com Network Supervisor.

■ Do not set the Webcache proxy port number to

65535. If you do, your Webcache will refuse to start and must be returned to 3Com. You may use any other numbers in the range 1024-8080 and 8090-65534. Future releases of the Webcache management software will prevent the value of 65535 being entered.
