What Values Can Be Assign to "X-Nginx-Cache" In .Htaccess File?

3 minutes read

In the .htaccess file, the "x-nginx-cache" header can have different values assigned to it. Some common values that can be assigned to this header include: "HIT" indicating that the cache was used to serve the request, "MISS" indicating that the cache was not used and the request was forwarded to the origin server, and "BYPASS" indicating that the cache was bypassed for the request. Other values may also be assigned depending on the server configuration and caching rules.


How to change x-nginx-cache to "REVALIDATED" in .htaccess file?

To change the x-nginx-cache header to "REVALIDATED" in the .htaccess file, you can use the following directive:

1

Header set X-nginx-cache "REVALIDATED"


Place this line in your .htaccess file in the root directory of your website. Make sure that you have the necessary permissions to modify the .htaccess file. Save the changes and test to make sure that the x-nginx-cache header is now set to "REVALIDATED" when accessing your website.


Note: This directive will only work if the X-nginx-cache header is already being set in the response headers. If the header is not being set by your server or proxy, you may need to adjust your server or proxy configuration to add this header before using the .htaccess directive.


What does "REVALIDATED" indicate about cache validation in x-nginx-cache in .htaccess file?

When "REVALIDATED" is indicated in the cache validation setting in x-nginx-cache in the .htaccess file, it means that the cache will be revalidated by sending a conditional request to the server to determine if the cached content is still valid before serving it to the user. This helps to ensure that users receive the most up-to-date content while still benefiting from the performance improvements of caching.


What is the significance of "STALE" value for x-nginx-cache in .htaccess file?

In an .htaccess file, the "STALE" value for the x-nginx-cache directive indicates that the cached version of a resource can be served even if it has expired or become stale. This can be useful when the server is experiencing high traffic or load, as serving a stale cached version can help reduce the response time and improve the overall performance of the website. However, it is important to carefully consider the implications of using the "STALE" value, as it may result in serving outdated content to users.


What is the purpose of setting x-nginx-cache to "HIT" in .htaccess file?

Setting x-nginx-cache to "HIT" in the .htaccess file is not typically done, as the x-nginx-cache header is used by Nginx servers to indicate whether a response was served from the cache (HIT) or not (MISS). The .htaccess file is used for configuring Apache web servers, not Nginx.


If you want to control caching behavior in Nginx, you would typically do so by configuring caching directives directly in the Nginx configuration file, rather than in the .htaccess file.


That being said, if you are using both Apache and Nginx together in a reverse proxy setup, you may need to set x-nginx-cache to "HIT" in the .htaccess file for some specific reason related to your setup. In general, however, this is not a common or recommended practice.
