As a user, I was using SSLUserName to determine identity. This worked
great when SSL termination happened on the same server as the
application, but when I terminated SSL on a reverse proxy and proxied
the request to a backend server, there was seemingly no way to fill
r->user on the backend, eg from a named header passed from the reverse

I fixed this with a noddy module that did that - pulled the value of a
header and puts it into r->user.

It would be good if there is a default module that could support that also.
