How to Install Squid Proxy Server on Ubuntu 16.04

October 9, 2020 Liquid Web

A Squid Proxy Server is a feature-rich web server application that provides both reverse proxy services and caching options for websites. This provides a noticeable speedup of sites, and allows for reduced load times when being utilized.

Squids reverse proxy is a service that sits between the Internet and the webserver (usually within a private network) that redirects inbound client requests to a server where data is stored for easier retrieval. If the caching server (proxy) does not have the cached data, it then forwards the request on to the webserver where the data is actually stored. This type of caching allows for the collection of data and reproducing the original data values stored in a different location to provide for easier access.

A reverse proxy typically provides an additional layer of control to smooth the flow of inbound network traffic between your clients and the webserver.

Squid can be used as a caching service to SSL requests as well as DNS lookups. It can also provide a wide variety of support to multiple other types of caching protocols, such as ICP, HTCP, CARP, as well as WCCP.  Squid is an excellent choice for many types of setups, as it provides very granular controls by offering numerous system tools, as well as a monitoring framework using SNMP to provide a solid base for your caching needs.
