Proxy Services

The proxy server is an internal application which processes the client workstation requests to
the Internet and provides the following services:
- Caching service. If the caching service is active, the proxy server keeps local copies of
the different client requests. In this way, it can serve a request by retrieving content from
previous requests instead of contacting remote servers. This significantly saves bandwidth
while increasing performance.
The caching service also provides statistics on Web traffic.
- Web access control. The proxy server can permit or block Web access for each user
