With an empty DATA frame, which is exactly how Im doing my interface. But it really sounds like a corner case. Metadata is much more likely to occur at the beginning of a new message than later, or especially the end.

I can see translating HTTP-like transactions to segments, and you would END_SEGMENT after each response. But sending an empty data frame for an empty response body is only 8 bytes. In the old currency that only buys you the string "HTTP/1.1 :v) .
