Subject Re: HttpAsyncClient 4.0-alpha3 and timeouts
Date Sat, 26 Nov 2011 19:12:49 GMT

I'm talking about response timeouts. I tried just using HttpCore and that
respected the response timeouts for my test. I used the NHttpClient example.
It could be an option to just use HttpCore but I was interested in using the
higher level connection support.

All I want to do is to be able to configure a response timeout of x seconds,
so if the web service takes more than x seconds to respond I get a timeout.
So the socket remains connected at all times but there is no response.

I suspect that I'm not explaining myself very well.
