We are seeing failures where ATS tries to resolve the origin domain defined in remap.config, instead of going to the local nginx. Our expectation out of these configurations is that, remap should only be used for request transformation, we need the outbound host header as in this case is `example.com` to be served via the nginx that runs **locally** on port 8000. What's currently happening is that ATS does not try to reach out to the local nginx in the first place instead, it DNS resolves `example.com` and requests that machine the domain points to, bypassing the parent configuration logic completely. -- This is an automated message from the Apache Git Service.
