I have mydomain.co registered with Godaddy. In the zone editor I have the @ record pointing to my cloud server. I would now like to redirect mydomain.co/blog to a different server where I'll host a wordpress blog. I cannot figure out how to do this on Godaddy. All Godaddy support pages describe buttons that do not exist on my domain control panel.

I'm sure my question is a dupe, but I just can't find the original.
