[Plugin: WordPress Varnish] More purge orders
-
Hello,
I added purges for the following pages to your plugin ::
posts
purge archives (https://domain/YYYY,https://domain/YYYY/MM)
purge categoriesplus I added support for a plugin called WordPress-Recent-Comments and another one called ajax-calendar.
I will send another version soon that purges all the blog when comment is added and plugin recent comments is activated (I know that this widget should be done with esi or ajax, but as this is not standard, your plugin should add support for that)
Here is the modified wp-varnish.php :
