I'm not sure how that actually works with http/1.1 - does it

Anyway, I'm not sure if you mean HTTP Proxy-Authorization there
or if it can be done another way, but if a side-effect of this
work on proxies is that that header field gets protected by a
TLS session between the client and proxy then that'd be a good
thing since sending Basic or Digest credentials in clear is not
a good thing for sure. (So maybe there will be one thing about
this proxy stuff that I do like:-)

I've never heard of that two-proxies-in-a-row wanting to use
Proxy-Authorization though and didn't think it could work.
