What is the SSI option?
Server Side Includes (SSI) is a simple server-side scripting language, which makes the maintainance of the site easier. The common elements throughout the site are put in separate files to save server resources. For instance, the header of your site will be loaded from the SSI file and will be automatically displayed on every page of your site, no matter how many pages you have. When you choose this option, you will receive two versions of the site. One will include html pages, which can be opened both locally and from the server. The second will use Server Side Includes (SSI). It is appreciated if you specify which elements should be included into the SSI.
