All calls for post do not user the referred proxy and go as if no proxy exists

Question

Hi All, we having some issues, i think is a tricky one

 

Our context in a RaspeberryPie Running Windows 10 IOT CORE We need to use a proxy for internet access.

--> c# code that sends a post to a webservice 

 HttpClient _httpClient = new HttpClient();
  HttpResponseMessage httpResponse = await _httpClient.PostAsync(_urlBase, new StringContent(postData, Encoding.UTF8, "application/json"));

--> It works

Our Problem 

 Even after setting proxy with "netsh winhttp set proxy ..."", Output bellow shows proxy configured in system. All calls for post do not user the referred proxy and go as if no proxy exists
 "
  Current WinHTTP proxy settings:
     Proxy Server(s) :  192.168.1.36:8080
     Bypass List     :  (none)
 "
For us any solution (code, configuration, or even changing IOT Core to other flavor like IOT PRO) its ok as long as it solves the problem

Thanks,

Joao

Answer 1

Hello Joao,

I run your C# code piece in UWP app on Raspberry Pi and set fiddler as the proxy following this tutorial. Then fiddler can capture the HTTP POST request.

For more detailed information about your settings, the HTTP POST request is not routed to your proxy server(192.168.1.36:8080)?  How did you check this?

Best regards,

Rita

Answer 3

Hi,

the registry settings are on (as indicated) the win http are set. But the problem persists.

Already tried restart and no luck. When running code in visualstudio (remote debug on rasp) the post runs always successfully (making the call without going by the proxy)

Any help would be great.
