To enable SSI for .html files in a given directory, either edit or create a file called .htaccess, and add the following line:
AddType text/x-server-parsed-html .htmlTo enable this feature for your entire site, you only have to add this .htaccess information in your website's main directory.
<body> <!--#include file="menu.html" --> </body>
The file named "menu.html" is located in the same directory.
Also the folder "Adobe_Style_Menu" is located in the same directory.
