[WP8.1]: Changing Windows Phone 8.1 WebView default User-Agent in all outbound HTTP requests

Recently, I’m developing Windows Phone 8 app which hosting our cloud services. We need to add some custom HTTP Headers in to requests. Unfortunately, Windows Phone 8 WebBrowser control doesn’t have properties to set custom User-Agent by default. The only way you can do is the method:

webBrowser1.Navigate(new Uri("https://basquang.wordpress.com/2014/04/26/wp8-1-changing-windows-phone-8-1-webview-default-user-agent-in-all-outbound-http-requests/", UriKind.Absolute), 
null, "User-Agent: your custom user-agent");

But with this method, you are able to pass your custom user-agent in first request only. With outbound HTTP request, meaning all web link in your site, the webBrowser1 will using device’s default User-Agent.

You can check your current user-agent here: http://whatsmyuseragent.com/

By the release of Windows Phone 8.1, now you can set your custom User-Agent for entire process by using Win32 API: UrlMkSetSessionOption

Using following code to make your user-agent by default for all outbound HTTP request in WebView control on Windows Phone 8.1

[DllImport("urlmon.dll", CharSet = CharSet.Ansi)]
private static extern int UrlMkSetSessionOption(int dwOption, string pBuffer, int dwBufferLength, int dwReserved);

const int URLMON_OPTION_USERAGENT = 0x10000001;
public void ChangeUserAgent(string Agent)
   {
      UrlMkSetSessionOption(URLMON_OPTION_USERAGENT, Agent, Agent.Length, 0);
   }

void MainPage_Loaded(object sender, RoutedEventArgs e)
   {
      ChangeUserAgent("My Custom User-Agent");
      wb.Navigate(new Uri("https://basquang.wordpress.com/2014/04/26/wp8-1-changing-windows-phone-8-1-webview-default-user-agent-in-all-outbound-http-requests/", UriKind.Absolute));
   }

Hope this help!
