When creating a webrequest in c#, how do I get the appropriate proxy information?

I want to create a webrequest with the current proxy information.  I've tried several routines to get the current proxy information but I'm not getting what I expected.  

On this machine I have my connection proxy set to "No Proxy" (Firefox - Tools/Options/connection settings).  I do have data in the "Manual Proxy Configuration", but with the "No Proxy" option selected the manual proxy information is grayed out.  I would expect in this configuration for the proxy to be null.  However, when I use GetSystemWebProxy or similar functions it is returning the manual proxy information, not null as I would expect.  What is the proper "GetTheProxy()" routine in the example below?

Example Code:

 public HttpWebRequest GetWebRequest(string url)
        {
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
            IWebProxy theProxy = GetTheProxy();
            req.Proxy = theProxy;
            req.Timeout = 10000;
            return req;
        }

public iWebProxy GetTheProxy()
       {
            ??????
       }

I'm not 100% certain, but I would expect that the decision whether to use a proxy or not is application-specific - meaning that your FireFox settings really only apply to FireFox (plus the Microsoft docs say specifically that GetSystemWebProxy returns Internet Explorer's settings - http://msdn.microsoft.com/en-us/library/system.net.webrequest.getsystemwebproxy.aspx)

Thanks tgerbert.  I didn't realize the I would need to change the connection properties in both, IE and FF and I still had the proxy configured for IE.  I assumed that both would use the same connection properties.  I changed IE and it worked as expected.

Cheers!

If it makes sense, you might consider a configuration screen allowing the user to set proxy parameters, and just have it default to what's returned by GetSystemWebProxy.
