GZIP was originally created by Jean-loup Gailly and Mark Adler for file compression in UN*X systems. In Linux, we frequently encounter files with the .gz extension, which are in GZIP format. Today, it has become one of the most widely used data compression formats on the Internet, or more precisely, a file format. GZIP encoding in the HTTP protocol is a technology used to improve the performance of web applications. Large-scale websites commonly use GZIP compression to provide users with faster loading speeds. This is typically a feature installed on web servers: when a user visits a website hosted on the server, the server compresses the webpage content and transmits it to the user’s browser for display. Generally, plain text content can be compressed to about 40% of its original size, which significantly speeds up transmission and ensures that the page appears quickly after you click the URL. Of course, this also increases the server’s load. Typically, server environments come with this compression module pre-installed.
