This is driving me nuts!! Anyone, please help...
I would like to send an HTTP GET request to a server over SSL and I am using
System.Net.HttpWebRequest to do so. I have the valid certificate installed to
the Current User. That's for sure because I am able to access the same
resource using IE. But my code isn't working. Everytime it receives a
WebException, whose status is ConnectFailure, which means "The remote service
point could not be contacted at the transport level.", also whose message is

你给得如何设定empty proxy神奇的解决了我的问题，谢谢谢谢
by the way, 前面说得loading cert是optional的，只对client authentication有必要
，
你一定是知道得啦，写出来为了后来者:P。从server处获得的cert必须首先安装在受信任
德certificates store里面，否则不工作。

Thanx. will try it tomorrow.
BTW, do you know much about the certificates?
If I have imported a certificate to the Current User Personal store,
is there anything else I need to do in order to utilize this cert
when accessing via HTTPS?

hey, thanx for replying.
no i didn't
when debugging, i found out that the Proxy proterty of the instance
of HttpWebRequest is always our proxy server, no matter how I set
it or disabled it at IE. Then I tried to set this property with
a blank proxy:
req.Proxy = new WebProxy();
but it didn't help.
Now I am at home, am testing with the same server, it's an different
exception message I got. Instead of ConnectFailure, it's TrustFailure.
So I am sure now it's about the network settings I had at offi
