which HTTP requests are not redirected to the cache servers, enter the following
command in Configure mode:
Define destination sites to which
HTTP requests are sent directly.

Proxy Server Redundancy

Some networks use proxy servers that receive HTTP requests on a non-standard port
number (i.e., not port 80). When the proxy server is available, all HTTP requests are
handled by the proxy server. The SSR can provide proxy server redundancy by
transparently redirecting HTTP connections to the cache servers should the proxy server
fail. To achieve this, the SSR must be configured to redirect HTTP requests on the (non-
standard) HTTP port used by the proxy server.
To redirect HTTP requests to a non-standard HTTP port number, enter the following
command in Configure mode:
Specify non-standard HTTP port.

Distributing Frequently-Accessed Sites Across Cache Servers

The SSR uses the destination IP address of the HTTP request to determine which cache
server to send the request. However, if there is a Web site that is being accessed very
frequently, the cache server serving requests for this destination address may become
overloaded with user requests. You can specify that certain destination addresses be
distributed across the cache servers in a round-robin manner.
To distribute a specified destination address across cache servers, enter the following
command in Configure mode:
Distribute destination address
across cache servers.

Monitoring Web-Caching

To display Web-caching information, enter the following commands in Enable mode.
Show information for all caching
policies and all server lists.
