Question

I have a HyperlinkButton in my Silverlight project. Clicking the link will open the URL in a new page:

<HyperlinkButton x:Name="Button1" Content="Click" 
  TargetName="_blank" Click="Button1_Click" 
  NavigateUri="http://www.example.com" />

When I click the button, I want a (second) asynchronous request to be fired to a statistics server:

private void Button1_Click(object sender, RoutedEventArgs e)
{
   WebClient webClient = new WebClient();
   webClient.Headers["content-type"] = "application/x-www-form-urlencoded";
   webClient.Encoding = Encoding.UTF8;
   webClient.UploadStringAsync(destURI, "POST", "action=click" + 
       "&id=" + id);
}

However, if I check with FireBug, this request is never fired. How can I make this request work?

Note: I have already checked that the destination page can receive requests. The destination has a correct clientaccesspolicy.xml and crossdomain.xml.

Argh. The problem is with Firebug. The browser window loses focus and requests are no longer captured. Wireshark shows that the request fires correctly.
