How does Squid proxy work?
Squid is a Unix-based proxy server that caches Internet content closer to a requestor than its original point of origin. Squid works by tracking object use over the network.

A transparent proxy, also known as an inline proxy, intercepting proxy or forced proxy, is a server that intercepts the connection between an end-user or device and the internet. It is called “transparent” because it does so without modifying requests and responses.
What is SSL bumping?
SSL Bumping. Squid service that is used for intercepting the content of encrypted HTTPS sessions. in the Squid service to handle encrypted connections. If SSL Bumping is not configured, the proxy server cannot intervene in the process of establishing an encrypted connection.
Why is squid so slow?
Check CPU and RAM Usage It might be you are hitting the limits of the available hardware. This can be checked by running htop command on the proxy box and analysing the CPU usage of squid and wsicapd processes. The more users are using the proxy, the more CPU resources will be consumed.
What is squid forward proxy?

How much disk space is required for squid to cache data?
Because the connection is normally not used to its upper volume limit, it can be assumed that the total data volume handled by the cache is approximately 2 GB. Hence, in this example, 2 GB of disk space is required for Squid to keep one day’s worth of browsing data cached.
How does the cache_Mem parameter work in squid?
The cache_mem parameter does NOT specify the maximum size of the process. It only specifies how much memory to use for caching “hot” (very popular) replies. Squid’s actual memory usage is depends very strongly on your cache_dir sizes (disk space) and your incoming request load.
How can I reduce squid’s memory usage?
Squid’s actual memory usage is depends very strongly on your cache_dir sizes (disk space) and your incoming request load. Reducing cache_mem will usually also reduce the process size, but not necessarily, and there are other ways to reduce Squid’s memory usage (see below). See also How much memory do I need in my Squid server?.
