Both Squid and the app are slightly broken.

  The Proxy-Connection headers are not supposed to be sent. Your app and
squid are both supposed to send only Connection: and accept either
Proxy-Connection: or Connection: back.

  There are some versions of Squid-3 prior to 3.1.7 which unfortunately
send Proxy-Connection so it will be around for a while. If you have one
please upgrade or apply patch:
