Install Fikker Cache to build a self-built CDN to accelerate. Because I have been busy modifying the website theme in the past few days, I quickly share this self-built CDN tool now. After carefully studying the introduction on the official website, I found that Fikker is easy to install and use. It is a good software for building your own CDN. According to the official website, Fikker is a professional-level website cache (Webcache) and reverse proxy server software (Reversed Proxy Server) for CDN/webmasters.
