Server Side Includes (SSI)
Server Side Include (SSI) is an HTML comment that directs the Web server to dynamically generate data for the Web page each time it is requested. The basic format for SSIs is as follows:

     <!--#COMMAND PARAMETER="value"-->

Where #COMMAND is any server side command supported by the Web server. The simplest command is #INCLUDE, which inserts the contents of one file into another. Include is very useful for ensuring that each pages headers and footers are the same throughout the website. To change an included header or footer you only have to modify the included file, instead of updating each Web page individually.
