Server Side Includes (SSI) is a common server-side scripting language, used to add the content of one file inside of a second file. It is utilized primarily with online content and it can help make a static HTML website a lot more dynamic. If you need to have a daily quote displayed on numerous web pages within your website, for example, you can create a text file and replace the quote in it every day. All the webpages in which this file is included will show the updated quote, so you will not need to alter them personally each time. SSI may also be used to incorporate the output of basic functions instead of a static file - for example, the visitor's IP address, a hit counter or maybe the current date and time. This way, you can make your internet site seem far more professional and much more attractive to the website visitors. Web pages that employ SSI get a .shtml extension.
