Using Environment Variables with SSI
Apache environment variables can be used in HTML by utilizing Server Side Includes (SSI).
In the HTML code of the page, a special SSI tag can be included that Apache will automatically substitute into the HTML when the page is served from the server. The SSI tag looks like this:
<!--#echo var="DEVICE_NAME" -->By default, SSI is not enabled on HTML pages. SSI can be enabled in one of several ways.
- To enable SSI for a single page, the extension of the HTML document can be changed to .shtml. The .shtml extension causes Apache to process the SSI tags inside the HTML content of the document.
- To enable SSI for a directory, a .htaccess file can be created in the directory that includes the
Options +Includedirective. - To enable SSI site-wide, the Apache configuration can be modified.
