Varnish purger

What is this?

This is the Varnish purger for the Purge module.

Project name and module name

Because of some bad naming in the start - the project name is varnish_purge, but the module itself is called varnish_purger. Sorry for that, but it's hard to move namespace after you have registred one.

Varnish configuration

To work with cache tags you need to have a Varnish vcl-file that implements is, here is a suggestion for defaul.vcl for Varnish 4 and using BAN.

Supported Varnish versions

This module has nothing to do with which version of version you are using, as long as Varnish supports BANs, this module should work - so use Varnish 3 and up with this module.

Image bans

Since release of 8.x-1.7 we now have basic support for image bans with the sub module varnish_image_purge, using a VCL setting like the following:

sub vcl_recv {
  if (req.method == "URIBAN") {
    ban("req.http.host == " + req.http.host + " && req.url == " + req.url);
    # Throw a synthetic page so the request won't go to the backend.
    return (synth(200, "Ban added."));
  }
}
