Header unset ETag FileETag None
A more nuanced solution specific to Apache involves the SSILastModified directive. By turning this on, the server will send a Last-Modified header based on the last modification time of the processed SSI document (including any included files). This allows browsers and proxies to cache the page but check for updates intelligently.
Ensure your server (Apache/Nginx) is configured to parse SSI. In Apache, this often requires Options +Includes and AddType text/html .shtml . 4. Direct Server Check
One of the most overlooked aspects of is the content inside the includes. For example, if you have: view shtml updated
The most straightforward method: clear your browser's cache. While effective, this can be frustrating for end-users, so it's best used for troubleshooting rather than as a primary strategy.
: The core feature uses the config and flastmod SSI commands to automatically pull the file's timestamp from the server.
Advanced users can write custom user scripts that periodically check for changes. On platforms like Wikipedia, user scripts such as "Ahecht's Refresh" add options to "purge all" and "null edit all" for template and category pages, effectively clearing caches to show the latest version of a page.

If you have modified an .shtml file or an included file, follow these steps to ensure the changes are live: 1. Clear Browser Cache
He pressed F5 .
: You can localize or style the date string (e.g., "YYYY-MM-DD" vs. "Month DD, YYYY") by adjusting the timefmt parameter. Ensure your server (Apache/Nginx) is configured to parse SSI

Even when the server has a newer version, your browser may send an If-Modified-Since header. If the server incorrectly reports “Not Modified” (304), the browser keeps using its cached copy.
<FilesMatch "\.(shtml|shtm)$"> Header set Cache-Control "no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires "0" </FilesMatch>
Risk: This command prints all server environment variables, including database credentials and API keys. Use code with caution.
