dear all..

i am connecting to a web service to get a specific results and my windows applications download many files according to response from web-service

the problem appears only when using a proxy in my internet explorer using program "analog proxy"
this is the steps i made:
tools->internet options->connections->Lan settings-> and i checked use proxy server for Lan..... with address: and port:6588

my code to connect to web-service is:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("");

IWebProxy proxy = request.Proxy;
if (proxy != null)
    MessageBox.Show("Proxy: {0}"+ proxy.GetProxy(request.RequestUri));
    MessageBox.Show("Proxy: {0}Proxy is null; no proxy will be used");

WebProxy myProxy = new WebProxy();
Uri newUri = new Uri("");
// Associate the newUri object to 'myProxy' object so that new myProxy settings can be set.
myProxy.Address = newUri;
// Create a NetworkCredential object and associate it with the
// Proxy property of request object.
myProxy.Credentials = new NetworkCredential("john", "johngra");
request.Proxy = myProxy;

and in app.config i put the following line

  <defaultProxy enabled="true" useDefaultCredentials="true" >


i got this error:

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it

Are you actually running a proxy server on one of your LAN computers? Or are you just trying to route traffic through another computer by IP address?

i am making the proxy on my PC only through internet explorer and analog proxy program

and i am trying to connect to internet through this proxy

You may need to read up on what proxy servers are:

Proxy Server[^]

On the computer that you are trying to connect to and make the proxy, it MUST be running a proxy server. This is a piece of software that re-routes requests. In your case, the computer needs to have a proxy server INSTALLED on it, and configured, to route traffic. Then your other computer can use it as a proxy server. Otherwise it will give a the "unable to connect" message that you are getting.

At the bottom of the link I gave there are links to servers that you can install. You have to be physically at the machine ( in order to install it, or have some kind of remote desktop access. I'm not sure what you mean by "analog proxy program"?

the analog proxy is a program,

i will check your solution now

thanks for your help

sorry i pasted a wrong url first
the url is
The WebRequest object has a useful property DefaultWebProxy

This returns the IProxy object you're trying to configure based on your systems proxy settings.[^]
