I think that with long polling the connection is closed once a response =
is received and a new request made straight after so you actually don't =
need to keep the original request open - you want to end it.

It's really not so hard to do this in JMeter - just setup a thread to =
call the endpoint and let it do what it does by default when making a =
standard HTTP request. The way JMeter loops by default will give you =
what you need to simulate long polling - all the clever stuff is server =
side, not client.

Just setup a simple thread group with this one call in it and nothing =
else. Put your other logic in a different group.
