One common method of caching content for websites is via the use of reverse proxy caching. Common examples of this are
Varnish and
Nginx. These systems allow a website to update content and have the visitor's experience cached without the need for complex plugins storing the files locally and using up a user's disk space.
The Remote Cache Purger plugin sends a request to delete (aka flush) the cached data of a page or post to remote server(s).
How It Works
Manually
No special instructions apply.
Requirements
- A server based proxy cache service (only Nginx for now) which responds to PURGE request.
