Which caching proxy for the web supports HTTP, HTTPS, FTP, and more, reducing bandwidth by caching and reusing content?

• A. Varnish
• B. Nginx
• C. HaProxy
• D. Squid

Answer: (D)

Caching proxies reduce bandwidth by storing copies of requested content so repeated requests can be served from the local cache instead of fetched again from the origin. Squid is a long-standing caching proxy designed to handle web traffic and optimize it by caching HTTP content and serving it quickly on subsequent requests. It supports HTTP and HTTPS (via TLS/SSL tunneling with CONNECT) and can proxy FTP as well, making it versatile for multiple protocols. This combination of purpose-built caching and multi-protocol support is why Squid is the best fit for a web caching proxy that lowers bandwidth by reusing content. Other options are more focused on HTTP acceleration, general web serving, or load balancing, rather than caching across a broad set of protocols.
