I have created my own Wordpress plugin for Google update cache.
However I'm not sure is my plugin work or not... whenever I update it, it doesn't change for a while. Sometimes it take less than 5 minutes to change, and sometimes it takes more than 10 minutes.
I always refresh my CDN site after I update my post, so I'll know my plugin is working if a website doesn't automatically updated from Google cache CDN site when it is visited.
So my question is:
Will our site be auto-updated from Google cache CDN site whenever we visited our CDN site?
there's no document about it, but I already talked with some developer who knows about this stuff.
