Hi. I submitted this fix a few months ago but it's been held up on not being tested on multiple platforms.
I've built it on Linux (Fedora) and OpenBSD successfully, but that's it. If someone can build it on Windows, MacOS, and Solaris that would be handy. The fix is here. It provides API hooks for 1.5 and 2.0 to set QoS on sockets. https://issues.apache.org/bugzilla/attachment.cgi?id=25700 The bug is here: https://issues.apache.org/bugzilla/show_bug.cgi?id=42848 Thanks.
