The root_path option for domain_remap seems to serve two purposes:
- provide the first component (version) for the backend request
- be an optional leading component for the client request, which
should be stripped off
As a result, we have mappings like:
c.a.example.com/v1/o -> /v1/AUTH_a/c/o
instead of
c.a.example.com/v1/o -> /v1/AUTH_a/c/v1/o
which is rather bizarre. Why on earth did we *ever* start doing this?
Now, this second behavior is managed by a config option
(mangle_client_paths) with the default being to disable it.
Upgrade Consideration
=====================
If for some reason you *do* want to drop some parts of the
client-supplied path, add
mangle_client_paths = True
to the [filter:domain_remap] section of your proxy-server.conf. Do this
before upgrading to avoid any loss of availability.
