Not that I have ever find. It was on my to-do list at a prior job, but never found time. My boss even had a nick-name for the idea “WWW Server”, short for “world’s worst web server” 
I think the fundamental problem is that there is no web server anywhere that was designed with this kind of idea in mind: “when you respond to this specific upcoming request, drop the connection halfway through sending the headers”, or “never finish sending the body”, etc…
