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.
■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.
■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.
