Caching Proxy Help

Using Caching Proxy as a Transparent Proxy Server

Transparent proxy means that the client software does not need to know that the intermediate proxy server exists. Normally, if a client browser uses a proxy server (in a forward proxy configuration), then the browser must be configured with address and port number of the proxy server. With transparent proxy, client browsers do not have to be configured to target the proxy server.

Transparent proxy is currently available only on the AIX platform.

In a transparent proxy scenario, a router or switch in the network is set up to redirect port 80 traffic to the Caching Proxy server instead of to its next network hop. The Caching Proxy server accepts all of this traffic, regardless of its actual destination, and processes each request.

Configure the Caching Proxy as a transparent proxy using the Proxy Configuration, Proxy Performance form. On the form, click the Run as a transparent proxy check box and click Submit to update the ibmproxy.conf file. You must then stop the Caching Proxy server completely and start it again (using the Restart icon is not sufficient) to effect the setting change.
