Vimexx hosting compatibility

[piotrbak]

Vimexx hosting is using Varnish on their servers. In order to purge their cache, we need to add additional headers to our requests: host-ZXCS: X-Purge-ZXCS: true

Current state Right now we can use the following snippet to make the compatibility: http://snippi.com/s/21eii77

Ideal state Make automatic detection and integration with this hosting provider.

@piotrbak Is there a way to know a website is hosed on Vimexx?

The Vimexx-specific headers were set using:

add_filter('rocket_varnish_purge_headers', 'filter_rocket_varnish_args' );
function filter_rocket_varnish_args( $headers ){
    $headers[ 'X-Purge-ZXCS' ] = 'true';
    $headers[ 'host-ZXCS' ] = $headers['host'];
    return $headers;
}

However, adding Vimexx's IPs using our helper plugin, didn't purge the cache. What did was:

• setting the $scheme to HTTPS:

  add_filter( 'rocket_varnish_http_purge_scheme', function( $scheme ){
  $scheme = 'https';
  return $scheme;
  });

• replacing the IP of the $purge_url with Varnish's TLD:

  
  add_filter( 'rocket_varnish_purge_url', function( $purge_url ) {
  $purge_url = str_replace( '185.104.28.118', 'varnish3.zxcs.nl', $purge_url);
  return $purge_url;
  });
