Installation

If you are using zc.buildout to manage your project, you can do this:

• Add stxnext.varnishpurger to the list of eggs to install, e.g.:

  [buildout]
  ...
  eggs =
      ...
      stxnext.varnishpurger
  

• If you're using plone.recipe.zope2instance recipe to manage your instance add this lines to install a ZCML slug:

  [instance]
  recipe = plone.recipe.zope2instance
  ...
  zcml =
      ...
      stxnext.varnishpurger
  

• Re-run buildout, e.g. with:

  $ ./bin/buildout
  

You can skip the ZCML slug if you are going to explicitly include the package from another package's configure.zcml file.

Finally go to portal_quickinstaller and install stxnext.varnishpurger product.

Usage

After installation one new viewlet above object's content will be displayed. The viewlet contains a link to purge content of actual url from varnish cache. In site properties there is additional configuration where you can define the address of varnish instance url (by default: localhost:6081).

The varnish configuration file should contain customized vcl_recv subroutine to purge given object by it's UID:

sub vcl_recv {

        ...

   if (req.request == "PURGE") {
        if (!client.ip ~ purge) {
             error 405 "Not allowed.";
            }
        purge("obj.http.X-Context-Uid ~ " req.url);
            error 200 "Purged";
        return(lookup);
   }

    ...

}
