title: How to programmatically login into a website that does not return an html response using c#? It hangs when calling GetResponse()
body: <p>I am trying to programmatically login into a website ("<a href="http://www.smscountry.com" rel="nofollow noreferrer">http://www.smscountry.com</a>") using C#, but the program hangs at the second GetResponse() request, where I try to login by POST method and filling the form fields.</p>
  
  <pre><code>        public String GetWebContent(String username, String password)

  <p>I don't understand what the problem is. I think it might have something to do with the page getting redirected an not returning an html response, but I am not completely sure. Is there a solution to this problem? Or is there any other way I can login into this particular website?</p>
