Server side includes are variables that come from the server. You should rename your html pages to shtml if you use SSI.
What if I don't want to use .shtml?
Some common SSI codes:
<!--#echo var="HTTP_REFERER" --> |
(referring URL) |
<!--#echo var="REMOTE_ADDR" --> |
(visitor's IP address) |
<!--#echo var="REQUEST_URI" --> |
(requested URL) |
<!--#echo var="HTTP_HOST" --> |
(server name) |
<!--#echo var="HTTP_USER_AGENT" --> |
(visitor's browser) |
<!--#echo var="REDIRECT_STATUS" --> |
(redirect status code) |
<!--#echo var="DATE_LOCAL" --> |
(visitor's date and time) |
