Purges the nginx proxy cache when you publish or update a post or page.
After your publish or update a page or post this plugin creates a list or url's to purge. For instance if the page is http://www.example.com/about/, the plugin creates a url of http://www.example.com/purge/about/. After creating all the urls to purge, the plugin opens each of the urls. It is critical that you have nginx configured with a location of /purge/. You can manually purge a page by opening the purge url directly.
