Using Server Side Includes with HTML Files Updated on March 10, 2026 by Carrie Smaha 0 Minutes, 54 Seconds to Read Typically, when you use Server Side Includes, you’ll save the file with the shtml extension. This tells the server that it contains a SSI. If you have lots of files, renaming them with the shtml extension can be tedious. You can easily set up a htaccess rule to allow SSI with html files. If you are not familiar with server side includes, please read our article. Please keep in mind, if you do not have to do this, it is not recommended. Since you are directing the server to parse all HTML files it can slow down page load speeds.
