why won't WebProxy BypassProxyOnLocal work for me?
I'm trying to get HTTP calls I'm making from C# .NET to a local address (localhost:3000) to use the proxy I set (so I can go through fiddler). Using the below WebProxy approach works开发者_StackOverflow中文版 if I point the target URL to a non-local address, however I need to point it to a local web-server I have (at localhost:3000), and when I do this the request is not going through the proxy.
I have inlcuded the "proxyObject.BypassProxyOnLocal = false". This should make it work no? Any suggestions re how to force the request to go through the WebProxy for http calls targetting a local address?
WebProxy proxyObject = new WebProxy("http://localhost:8888/", false);
proxyObject.Credentials = new NetworkCredential();
proxyObject.BypassProxyOnLocal = false;
WebRequest.DefaultWebProxy = proxyObject;
var request = (HttpWebRequest)WebRequest.Create(targetUri);
// I also included this line as a double check
request.Proxy = proxyObject;
Subsequent calls do not go through the proxy however, such as when I do:
var res = (HttpWebResponse)req.GetResponse();
thanks
I get around this simply by appending a "dot" to localhost, so instead of accessing "localhost", I try to access "localhost." (notice the dot at the end of the hostname)
Credit where credit is due: I got this unusual tip from this thread http://www.west-wind.com/weblog/posts/2009/Jan/14/Monitoring-HTTP-Output-with-Fiddler-in-NET-HTTP-Clients-and-WCF-Proxies#596591
Works fine!
See explanation on https://docs.telerik.com/fiddler/observe-traffic/troubleshooting/notraffictolocalhost
Internet Explorer and the .NET Framework are hardcoded not to send requests for Localhost through any proxies, and as a proxy, Fiddler will not receive such traffic.
The simplest workaround is to use your machine name as the hostname instead of Localhost or 127.0.0.1. So, for instance, rather than hitting http://localhost:8081/mytestpage.aspx, instead visit http://machinename:8081/mytestpage.aspx.
