Using Server Side Includes (SSI)
General information
Server Side Includes (SSI) are instructions that are placed
in Web pages and evaluated on the server while the pages are
being served. They allow you to include other files, such
as header and footer snippets, or to show the current date
and time or last-modified date of a file.
Using SSIs
In order for SSI to work, the file name of your Web page needs
to have the extension .html (e.g. index.html, resume.html).
Make sure to include the SSI directives in the HTML of your
Web page. To do that in Dreamweaver and Frontpage, you need
to switch to Code under the View menu.
Examples:
|
|
| Today's date/time |
Current date/time:
<!--#echo var="DATE_LOCAL" -->
|
Current date/time:
04/25/02 08:02 |
| Today's date |
<!--#config timefmt="%A, %B %e, %Y" -->
Today is:
<!--#echo var="DATE_LOCAL" -->
|
Today is: Thursday,
