the twitter streaming api docs say "Parsers must be tolerant of occasional extra newline characters placed between statuses. These characters are placed as periodic "keep-alive" messages, should the stream of statuses temporarily pause. These keep-alives allow clients and NAT firewalls to determine that the connection is indeed still valid during low volume periods."
that's all well and good, but I'd like some clarification on some behavior I'm seeing. I never see newlines come through alone... rather I always see CRLF (carriage return + linefeed; adjacent) pairs (two chars) come through on 30 second intervals to "keep-alive." as a result, I've built my parser to consider the combination CRLF as the heartbeat. should I be doing this, or am I missing something along the way in which I should truly only ever be looking for LFs?
