Here's my situation:
I'm hosting my blog at blog.foo.com.
I have a completely different app on foo.com.
I want my blog url to be foo.com/blog.
I've set up a reverse proxy on foo.com so that foo.com/blog/123 is fetched from blog.foo.com/123. This is working.
The problem is that all the links generated in the blog still use blog.foo.com. I want them to instead use foo.com/blog. Is there a plugin that will do this?
(or: should I be using a different approach entirely?)
