more filters

[boyska]

Some sites needs a bit of tweaking to appropriately cache: for example, my site also has a custom feed (url: ?feed=premoderate) which is not purged by wp-varnish.
With a filter, I'll add this to "commonobjects".

I intend to work on this to propose a patch; but I'm asking for opinions here.

My proposal is to make a filter for every method like WPVarnishPurgeCommon: the filter will be on the list of "objects" to purge. Example:

<?php
function WPVarnishPurgeCommonObjects() {
    $objects = array('/?', '/feed/', '/feed/atom/', '/category/.*');
    $objects = apply_filters('wpvarnish_purge_commonobjects', $objects);
    foreach( $objects as $o)
        $this->WPVarnishPurgeObject($o);
}
?>

so my site can easily add an object to this array, purging what I need

Sounds like a good idea.

Right now, you could just add:

$this->WPVarnishPurgeObject("/?");

to the function.

I'm rather hesitant to hardcode something like this as even category, feed, etc could be in subdirectories, or, with different permalink structures, could be named differently. I think the base URLs need to be constructed taking some of the WordPress helpers into account and then perhaps an optional purge list could be added through the admin. That would allow for much better handling of various site configurations.
