Server Side Includes (SSI) is a simple interpreted server-side scripting language, used almost exclusively for the Web, and is embedded with a servlet tag.
The most frequent use of SSI is to include the contents of one or more files into a Web page on a Web server.
When a Web page is accessed by a browser, the Web server replaces the servlet tag in that Web page with the hypertext generated by the corresponding servlet.
