SSI is a type of HTML command that is a powerful tool for web developers. This command directs the web server to dynamically generate data for the website upon request.
In addition, SSI can be used to execute programs and insert results into the website. Some websites with SSI have extensions that end with “.shtml”. However, this is not a requirement. The varying extension filenames enables the web server to differentiate those pages that need to be processed before being sent to the browser.
