No. The first line of the HTTP response ("HTTP/1.1 200 OK" or
whatever) depends on the headers that the CGI returns to the
server (e.g. "Status: 500 Database screwed again").

Ideally you want it to be the same as the path MTU. I don't know a
good way of finding that out in uerland though.
There remains the issue of the last partial packet in a response,
though: you want that to go out immediately after the rest of the
data.
