Want to let them know that they are still sending too many keep-alive
headers?

More generally, how on earth does software manage to screw up something
simple like an HTTP header so much? Is it usually an application that
just appends duplicate headers to what was an existing and legitimate
header from a web server? Or are there known-to-be broken versions of
applications out there?
