I've been tinkering with https://debbugs.gnu.org/cgi/bugreport.cgi?bug=53941 off and on for a bit, but I'm not familiar enough with the `url' landscape to go all in. From your bug description, you seem to have a good handle on the `url-http' parts, so perhaps you're open to exploring ideas for improving the overall proxy situation `url'-wide. If so, I'd be willing to investigate how best to adapt `socks' to whatever you might propose. Just a thought, though (no pressure).

I'd say try to make both approaches work, and see which one results in the minimum set of changes. Thomas
