724 Guidelines for using Web caching/Proxy
N0008589 3.3
Consider the following guidelines when using web caching/proxy:
• You cannot use the web server installed on Business Communications Manager as a general
purpose HTTP server. It is only used by the Business Communications Manager web-based
management client and Web Cache services.
• If you want to run web sites on your network, you must have a separate HTTP server running
on a system other than the Business Communications Manager system. There are two options
available for the IP address you publish for your website. You can publish a separate IP
address for the HTTP server or you can publish the same IP address as your Business
Communications Manager.
To publish a separate IP address for the HTTP server, publish the IP address of the computer
on which you are running the HTTP server.
To publish the same IP address used for Business Communications Manager, set up a NAT
rule to change the public address of the HTTP server to the IP address of Business
Communications Manager.
• Some secure web sites are not accessible through the Business Communications Manager Web
Cache service. If you are having problems accessing a secure web site, turn off the Web Cache
service and try again.
• Web Cache is disabled by default.
To configure the Web Cache settings:
1 On the navigation tree, click the Services key and click the Web Cache heading.
The Web Cache Summary screen appears.
2 Configure the Web Cache attributes according to the following table. Refer to “Important Web
Cache considerations” on page 725 for more information on the Web Cache attributes.

this value.
