Hi.

Varnish cache PURGE does not work since Varnish 2.x. It seems like Varnish will not any more accept the MediaWiki format (according to http://www.mediawiki.org/wiki/Manual:Varnish_caching):

PURGE http://domain.com/url HTTP/1.0

But it will rather want a compliant request such as:

PURGE /url HTTP/1.0 Host: domain.com

I have modified the SquidPurgeClient.php to reflect the following:

public function queuePurge( $url ) {

  $url = str_replace( "\n", , $url );
  $urlArr = parse_url($url);
  if($urlArr['query'] != "")
     $urlQuery = "?" . $urlArr['query'];
  else
     $urlQuery = "";
  $this->requests[] = "PURGE " . $urlArr['path'] . $urlQuery . " HTTP/1.0\r\n" .
     "Host: " . $urlArr['host'] . "\r\n" .
     "Connection: Keep-Alive\r\n" .
     "Proxy-Connection: Keep-Alive\r\n" .
     "User-Agent: " . Http::userAgent() . ' ' . __CLASS__ . "\r\n\r\n";
  if ( $this->currentRequestIndex === null ) {
     $this->nextRequest();
  }

}

Which seems to successfully PURGE pages with Varnish 2.x and 3.x.

In addition I have done the following to the VCL to purge both entries for www.domain.com and domain.com:

if (req.request == "PURGE") {

  if (client.ip != "....<edited>....") {
     error 405 "Not allowed.";
  }
  purge("req.url == " req.url " && req.http.host ~ ^(www.)?" regsub(req.http.host, "www\.(.*)", "\1"));
  error 200 "Purged.";

}

Yours,

Mikael

Thanks Mikael! This works for me in MediaWiki 1.19.0 and Varnish 2.1.5.
