ApacheBenchmark test can not set -k (keep alive) option. not working!

[wubin1989]

I made a benchmark by ab, set -k option which could enable keep alive, but it wasn't work.
keep alive connection number was always 0.
Why? How can I enable keep alive in code?

Hmm, this seems to be due to ab using Http1.0 and hyper acting slight weird. To fix, you can add the header Connection, e.g.

response.set(hyper::header::Connection::keep_alive());

Thank you @Ryman
Do you mean hyper default connection is keeping alive?
Only in the case of doing benchmark using ab, I should add response.set(hyper::header::Connection::keep_alive());
otherwise I don't need this code (e.g. in real production environment).
Am I right?
