Squid is a caching proxy for the web that supports various protocols including HTTP, HTTPS, FTP, and more. It operates by storing frequently-accessed web pages locally, thereby reducing bandwidth usage and improving response times for subsequent requests. By caching and reusing content, Squid minimizes the need to fetch data from remote servers, resulting in faster page loads and improved network efficiency. This makes it particularly useful in environments where internet connectivity is limited or costly, as it helps optimize resource usage and enhances the overall browsing experience.
