How does Squid work?
Squid uses access control lists to determine who is allowed to connect to and use the proxy. localhost (the system where Squid is installed) as well as most local networks will already be able to access Squid without a problem, but additional networks and IP addresses will need to be configured in the ACL if you want to allow them access. The easiest way to do this is by adapting Squid’s internal IP network list to fit your own needs. You can also add additional network and IP addresses in this same section.
What is a squid?
Squid is a robust proxy server that supports caching for protocols like HTTP, HTTPS, and FTP. It has the ability to speed up web requests by caching frequently accessed websites, and serving that cache to requesting clients. This is a great way for networks to reduce bandwidth consumption and provide snappier response times for web browsing.

Prerequisites
Step 1 — Installing Squid Proxy
- Squid has many use cases beyond routing an individual user’s outbound traffic. In the context of large-scale server deployments, it can be used as a distributed caching mechanism, a load balancer, or another component of a routing stack. However, some methods of horizontally scaling server traffic that would typically have involved a proxy server h...
Step 2 — Securing Squid
- Most proxies, and most client-side apps that connect to proxies (e.g., web browsers) support multiple methods of authentication. These can include shared keys, or separate authentication servers, but most commonly entail regular username-password pairs. Squid allows you to create username-password pairs using built-in Linux functionality, as an additional or an alternative ste…
Step 3 — Connecting Through Squid
- In order to demonstrate your Squid server, you’ll use a command line program called curl, which is popular for making different types of web requests. In general, if you want to verify whether a given connection should be working in a browser under ideal circumstances, you should always test first with curl. You’ll be using curl on your localmachine in order to do this – it’s installed by …
Conclusion
- In this tutorial, you learned to deploy a popular, open-source API endpoint for proxying traffic with little to no overhead. Many applications have built-in proxy support (often at the OS level) going back decades, making this proxy stack highly reusable. Next, you may want to learn how to deploy Dante, a SOCKS proxy which can run alongside Squid for proxying different types of web traffic. …
Prerequisites
- To complete this guide, you will need: 1. An Ubuntu 22.04 server and a non-root user with sudo privileges. You can learn more about how to set up a user with these privileges in our Initial Server Setup with Ubuntu 22.04guide. You will use the domain name your_domainin this tutorial, but you should substitute this with your own domain name, or IP address.
