Single Site Purging

To purge the entire network you can restart/reload nginx.

There isn’t anything for purging all of a single site due to the number of URLs that need to be purged in a typical site. The proxy cache key is a MD5 of the URL so there is no direct connection between cached content and a particular site in the network.

Having said that, you could write something to go through all of the posts and build an array of URLs to be purged if the site did not have a lot of content. The readme has some documentation on the functions you could use to retrieve the URLs per post, page, etc.
