I know for a fact that some servers stream their responses back if you
stream your requests to it, but I never bothered to make a list. Is that
what you're asking? Which specific servers out there (e.g. Apache,
Netscape, etc) are actually capable of streaming? If that's your
question, I don't know because I never bothered to keep track. I just
know some of them do because I've seen it in my trace logs.

And which specific clients (i.e. browsers, e.g. Netscape, IE, Opera,
etc) stream (pipeline) their requests, I don't know either. I never
bothered to check as it's hard to tell from my trace logs (since each
HTTP request my proxy processes is handled separately).

But if you're asking whether streamed HTTP requests/responses actually
get packaged together into the same physical TCP/IP packet, I would
venture a guess and answer: "more than likely" (unless you've purposely
disabled the Nagle algorithm, which is highly discouraged).[1]

[1] The Nagle algorithm can be disabled by setting the TCP_NODELAY
option for a socket via 'setsockopt'. For more information regarding the
Nagle algorithm, see RFC 896.
