Using wildcard for expire pages [#2204567]

My drupal installation has this "structure":

- alias for nodes of type "canto" are like: archivio/canti/[node:title]
- on path archivio/canti I've a solr views with a list of "canto" nodes (so there paths like archivio/canti?page=X or archivio/canti?f[0]=my_field=value

I would like to add a Rule (or a custom module) that, when I save a node of type "canto" ask expire to purge all pages like "archivio/canti?*", but paths like "archivio/canti/*" should not be purged.

Which syntax should I use, from PHP, to obtain this result?

Thanks a lot for this great module.

Sergio

I'm curious about this, too; I've got a paged news feed with a similar structure and if you just update the first page stories get lost in the cracks.

I solvedin a "custom" way.
On a custom module, on hook_node_insert, update & delete, I call varnish function to purge pages based on regular expression, in this way (I use varnish):

<?php

/**
* Implements hook_node_insert
*/
function mymodule_node_insert($node) {
  mydmodule_purge_clear_cache($node);
}

/**
* Purge varnish cache
* @param type $node
*/
function mymodule_purge_clear_cache($node) {
  $varnish_host = _varnish_get_host();
  switch ($node->type) {
    case 'canto':
      $path = 'archivio/canti';
      // Clear the main page of node list
      varnish_purge($varnish_host, '^/' . $path);

      // Clear every "child" page of node list
      varnish_purge($varnish_host, '^/' . $path . '[^/].+$');

      break;
  }
}

?>
Attenction: this module does not call expire hooks.
