Deploying Transparent Proxy Server using SQUID (Minimum Configuration)
This section only describes the minimum configuration needed for Transparent Proxy Server. Tweaking and tuning would be discussed in later sections. The Proxy service is a service that manages requests on behalf of another service. For example- if we want to filter and manage web requests (usually tcp port 80), we assign 'another' service to oversee the task. The 'other' service is the Proxy server. One may think, why would I use a proxy when I can control and filter web traffic using Firewall. Well, the answer is Caching: The proxy server caches frequently accessed web elements in the RAM and Hard Drive of the computer. If a requested web element is found in the cache, the element is supplied to the user from the cache. Since the cached element is fetched from the LAN, the time is significantly reduced. This gives us two outputs. Speeds up the Internet browsing experience Saves bandwidth as the same element is not fetched over and over again...
