I guess you can also configure this by changing the machine.config file:
<system.net>
.
<defaultProxy>
<proxy usesystemdefault="false" />
.
</defaultProxy>
</system.net>

Subject: Re: [ADVANCED-DOTNET] Bypass http proxy server for intranet app
using remoting
I found out how to fix this, I just need to add the following two lines
of
code after obtaining the remote object,
HttpChannel theChannel = (HttpChannel)
ChannelServices.GetChannel("http");
theChannel.Properties["proxyName"] = null;
This tells the httpchannel not to go through a proxy server.
If you are interested, here is how i find it out.
After digging into the source code of HttpClientChannel, i found that it
used a WebProxy object to access any http resources. Here is how the
proxy
settings are obtained,
WebProxy defaultProxy = WebProxy.GetDefaultProxy();
if (defaultProxy != null)
{
Uri address = defaultProxy.Address;
if (address != null)
{
_proxyName = address.Host;
_proxyPort = address.Port;
}
}
UpdateProxy();
..
..
private void UpdateProxy()
{
if ((_proxyName != null) && (_proxyName.Length > 0)
&&
(_proxyPort > 0))
{
WebProxy proxy = new WebProxy(_proxyName, _proxyPort);
proxy.BypassProxyOnLocal = true;
String[] bypassList = new String[]{ CoreChannel.GetMachineIp
() };
proxy.BypassList = bypassList;
_proxyObject = proxy;
}
else
{
_proxyObject = new WebProxy();
}
}
Notice that, during this process, the GetDefaultProxy method reads the
nondynamic proxy settings stored by Internet Explorer 5.5 and create a
new
WebProxy object with that settings in the first place. But then the
UpdateProxy() method creates a new proxy based on that only keeping the
basic information but NOT including the BypassList.
This is why enabling/diabling proxy server from the IE->Tools-
>InternetOptions->Connections affects my application, but the bypass
list
on the Advanced dialog does NOT!!!
When reset the proxyName property to null, the UpdateProxy() method is
invoked again - this time creates a blank WebProxy() - allowing me to
bypass the proxy server from my client application.
Whew...
