Caching is the most important tool when it comes to website optimisation. Without any caching system, the website cannot be claimed to be perfectly optimised.

Then there is an essential type of cache known as a reverse proxy cache. Reverse proxy cache is implemented on the server-side that stores information on the client’s server.

Companies hide certain information on the website or block social media websites, so the productivity of the employee is not hampered. This is known as a forward proxy.
In contrast, a reverse proxy is placed between the company’s web server and the Internet. So, whenever Internet requests access to the company’s website, the reverse proxy server will filter the request before reaching the site.
