7. Select the Cache HTTP to enable caching of HTTP documents.

   If you decide that you want your proxy server to cache HTTP documents, determine whether it should always do an up -to-date check for the documents in the cache or whether it should check based on an interval. You can also enable or disable the Proxy Server from reporting cache hits to the remote server. For more information, see Caching HTTP Documents. The available options are:

   • Select the Always Check That The Document Is Up To Date option to ensure that the HTTP document is always up-to- date.

     • Select the number of hours from the Check Only If Last Check More Than drop-down list to specify the refresh interval for the proxy server. The up-to-date check is performed using any one of the following options:

       • Use Last-modified Factor. The last modified header that is sent by the origin server along with the document.

       • Use Only Explicit Expiration Information. The proxy server uses the Expires header to decide if the cache entry is fresh or stale.

       Select the Never Report Accesses To Remote Server option to prevent the proxy server from reporting the number of accesses to the remote server.

     • Select the Report Cache Hits To Remote Server option to track the number of times a document was accessed and report it back to the remote server.
