About Server Side Includes

Server Side Includes (SSI), a feature of certain web page servers, allow you to include a common function in a number of different web pages. Using SSI, you can quickly and easily insert or update design elements such as headers, footers, or navigation across many web pages.

A Server Side Include file works almost like an HTML file. The only difference is that with an SSI file, the server must look at each line in the file for SSI commands. If the server finds a command, it tries to execute it. The output of the SSI command will appear in the HTML text as if it were typed at the location of the SSI command. SSI files commonly have the extension .shtml at the end of their filename.

Note:
Not all web servers support SSI, and because of the increased load that SSI places on the server in some systems, some administrators disable it even when it is included as part of the server software.

SSI at IU

SSI is disabled on Pages and on the Windows Hosting Environment (WHE) at Indiana University. It is available on Webserve, but the #exec command is disabled. For more, see What are Server Side Includes, and how do I use them?
