Hi there, Can anyone guide me on the exact regex of " http://cdn.mysite.com " for the use of Kier's Post Content Find / Replace addon? This is the only way I can think of to mass change part of the img/attachments' URLs on my site. In case you need to know why do I need that: I used MetaMirror and [bd] Attachment Store to store all the attachments and images to my server and they are being cached by CDN. Now I installed SSL onto my site and am using CDN's Shared SSL (url: https://mysite.r.worldssl.net), unfortunately all my attachments and img URLs are " http://cdn.mysite.com/example.png " and they are broken. I need to mass change them from " http://cdn.mysite.com/example.png " to " https://mysite.r.worldssl.net/example.png ". Any help would be much appreciated, thank you!
