One other thing to consider here is whether the user+pass have to be
sent in the URL at all.

If possible, it would be better to use a cache_peer connection that
sends HTTP authentication headers to the upstream server. That gives you
ability to "internally" use the more secure forms of TLS which cannot be
MITM'd for the connection containing credentials.

Alternatively, you may be able to send a custom header with the
http_header_add mechanism with a custom value to the origin server for
processing.
