Yup. It's attached. (Took me quite a while to figure out how to work the
system.) It doesn't have a datacheck stage yet, I just wanted to pass along
the problem case to you -- when we do engineer a fix I'd be happy to improve
the test case.

BTW, here is a strace log of connecting to the actual CCProxy server.
My guess is that CCProxy is just broken by resetting the connection just
like that, but I'll leave it up to you whether we should support this kind
of situation or not.

I think the erroneous bit is that CCProxy doesn't reset the connection after
sending the 407, it only resets it after it gets more data. I am feeling
like that is very nonstandard behavior:

connect(3, {sa_family=AF_INET, sin_port=htons(8080),
sin_addr=inet_addr("10.114.25.113")}, 16) = -1 EINPROGRESS (Operation now in
progress)
poll([{fd=3, events=POLLOUT}], 1, 299995) = 1 ([{fd=3, revents=POLLOUT}])

Let me know. I'd love to close the bug out on my end. :)
