 * Using the top bar, trying to empty the cache, I can see the http request is sent
   to WordPress:
 * > – BereqURL /?vhp_flush_do=all&_wpnonce=d972c0f5ca
 * However, it doesn’t appear to result in a PURGE request being sent.
 * On the master domain, it works, a PURGE is correctly sent, and cache emptied.
 * Interestingly, emptying the DB cache (redis), is working correctly.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmultisite-subdomains-not-processing-empty-cache-instructions%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * You’ll need to dive into this section – [https://github.com/Ipstenu/varnish-http-purge/wiki#debugging](https://github.com/Ipstenu/varnish-http-purge/wiki#debugging)
 * Basically you want to watch the requests and see what IS sent and what isn’t.
 * It’s possible your cache rules are getting in the way, or your setup doesn’t 
   properly account for subdomains. Have you tried a MANUAL purge via command line?
 * `curl -X PURGE http://your_domain/`
 * or
 * `curl -X PURGE http://your_domain/.*`
 * Also does ANY purge work? Like when pages are updated?
