Make a blog in Phame and assign a CNAME, for example, blog.foo.com.
Now, if you look at these hyperlinks, they will be incorrectly routed to the blog CNAME, *not* the original Phabricator URL. In other words:
- If your blog does not have a CNAME, rFOO links to /diffusion/FOO correctly.
- If your blog *does* have a CNAME (blog.foo.com), rFOO links to /diffusion/FOO - but this is wrong, because the relative URL is now blog.foo.com, making the whole URL blog.foo.com/diffusion/FOO
The fix basically is:
- If an object is referenced by a post,
- AND a CNAME is set,
- The hyperlink must instead point to the FQDN of the object, not the relative URL.
