Hi,
I'm pretty sure this was working before upgrading to 0.9.3, so I think it's a new bug. Basically, we have several servers sitting behind a load balancer which can all be accessed using www1, www2, etc instead of www.
Enabling CDN support used to rewrite urls correctly even when accessed using www1, such as http://www1.androidpolice.com, but no longer does so. Here's a sample broken url: http://cdn.androidpolice.com/http://www1.androidpolice.com/wp-content/themes/ap1/images/tip_us.png. As you can see, instead of replacing www1.androidpolice.com, the cdn prefix is prepended instead, thus creating a 404.
Playing with the "Cache requests only for http://www.androidpolice.com site address" setting in Page Cache doesn't seem to change anything.
Any ideas? Can this be fixed?
