Key: TS-2877

Project: Traffic Server
Issue Type: Bug
Components: Tools
Reporter: Masaori Koshiba
It look like http_load wait until timeout when a keep-alive enabled server
returns empty body.
I build http_load from master branch (commit
90ff1a79015a73d7906170f05c3d36fd3127e7d1)
For example, setup a keep-alive enabled Apache and a url which return empty
body.
