title: Awesomium, change useragent and referrer
body: <p>I just started to use awesomium.
  I wanted to understand how to change user-agent and referrer.
  i need for example to initialize 5 istance o awesomium webcontrol and for each of them i need different user-agent and different referrer.
  this is my simple code</p>
  
  <pre><code>        private void newbrowser()
      {
              browser = new Awesomium.Windows.Forms.WebControl();
              browser.Paint += browser_Paint;
              browser.Location = new System.Drawing.Point(1, 1);
              browser.Name = "webControl";
              browser.Size = new System.Drawing.Size(1024, 768);
              browser.Source = new System.Uri("https://www.google.com/", System.UriKind.Absolute);
              browser.TabIndex = 0;
  
      }
  
      void browser_Paint(object sender, PaintEventArgs e)
      {
          browser.Paint -= browser_Paint;
  
          System.Collections.Specialized.NameValueCollection myCol =
              new System.Collections.Specialized.NameValueCollection();
          myCol.Add("Referer", "http://www.yahoo.com");
  
          browser.SetHeaderDefinition("MyHeader", myCol);
          browser.AddHeaderRewriteRule("http://*", "MyHeader");
      }
      private void button1_Click(object sender, EventArgs e)
      {
          newbrowser();
      }
  </code></pre>
  
  <p>these 2 lines give an error</p>
  
  <pre><code>        browser.SetHeaderDefinition("MyHeader", myCol);
          browser.AddHeaderRewriteRule("http://*", "MyHeader");
  </code></pre>
