Slight correction - SSI's will only work if you add .html and/or .htm for parsing html files. By default, only .shtml files are parsed with SSI. details in post #4383542 [webmasterworld.com].
Use file if the include is in the same directory, virtual if it's in some other directory than the current directory.
