The version of nc/netcat that is shipped with RHEL5 and RHEL6 (and based on the OpenBSD implementation of netcat) has this problem with HTTP/1.1. The upstream OpenBSD implementation fixed this problem in September 2006, but it never made it in to the RHEL releases. I’ve discovered there was a redhat bug opened recently to get this fixed. I haven’t explicitly tested it, but I think the version of nc included in OSX Mavericks may also suffer the same issue, based purely on running the ‘strings’ command against the nc binary. Debian/Ubuntu appear to use the NMap implementation of netcat, which doesn’t appear to offer proxy support, so technically they aren’t affected :) Simon
