How do I flush Nginx cache?

Overview. When caching is enabled, NGINX Plus saves responses in a disk cache and uses them to respond to clients without having to proxy requests for the same content every time.

  1. Find you cache path. It might be set in the variable fastcgi_cache_path. If not, the default seems to be /var/ cache / nginx /
  2. Remove the cache folder by executing the following command rm -rf /var/ cache / nginx /
  3. Restart Nginx to reenable caching .

Likewise, people ask, what is Nginx cache?

Overview. When caching is enabled, NGINX Plus saves responses in a disk cache and uses them to respond to clients without having to proxy requests for the same content every time.

One may also ask, what is Nginx Sendfile? Enabling sendfile By default, NGINX handles file transmission itself and copies the file into the buffer before sending it. Enabling the sendfile directive eliminates the step of copying the data into the buffer and enables direct copying data from one file descriptor to another.

In this way, how do I know if nginx is caching?

1) Adding cache status header You could also check your header by using Developer Tools in your browser (Firefox and Chrome can open dev tools with F12 ). The cache status could be one of the following: “ MISS ”, “ BYPASS ”, “ EXPIRED ”, “ STALE ”, “ UPDATING ”, “ REVALIDATED ”, or “ HIT ”.

How nginx processes a request?

1 Answer. Nginx uses the Reactor pattern. Basically, it's single-threaded (but can fork several processes to utilize multiple cores). The main event loop waits for the OS to signal a readiness event - e.g. that data is available to read from a socket, at which point it is read into a buffer and processed.
