<div dir="ltr">Hi,<div><br></div><div>Connections can be re-used if the responses of the previous request is consumed. That's how ApacheHttpClient works for SimpleConnectionManager.

this test is working fine on beta2 snapshot.<br>
<br>
Are you suggesting that the connections cannot be reused even within<br>
each test ? And it should not work ?<br>
