Resolve a url after a #302 redirect #Xamarin.MAC

Say you have a url, like bit.ly/whatever – then you might want to know what the final url of that url leads to – I wanted to do that using Xamarin.MAC -although I assume that Xamarin.IOS would be the same.

NSUrl url = new NSUrl (strUrl);

NSUrlRequest request = new NSUrlRequest(url);
NSUrlResponse response = null;
NSError error = null;
NSUrlConnection.SendSynchronousRequest(request,out response,out error);
if (error != null)
{
  UITools.MessageBox(error.ToString());
}
url = response.Url;
UITools.MessageBox(url.ToString());

The Objective C code that I copied this from was as follows:


NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:orinigalURL 
* cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:15.0];
[request setHTTPMethod:@HEAD];
NSURLResponse *response = nil;
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSURL *finalURL = response.URL;

As it turned out, the error was actually that I had to add this to my info.plist

<key>NSAppTransportSecurity</key>

<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
