title: navigating to same page in windows phone 8
body: <p>In my WP8 app, i have situation where i have to navigate from one page to another and afterwards i need to reload the same page for some reasons.</p>
  
  <p>MainPage.xaml --> Page1.xaml --> Page1.xaml --> Page1.xaml</p>
  
  <p>When user press the backkey should go back to "MainPage.xaml" page.</p>
  
  <p>I tried using the <code>NavigationService.navigate()</code> for navigation, some reason i couldn't able to reload the page. If i pass any unique query strings (eg: Guid) with navigation url, i am able to reload the page. But, when i press back button - it never goes back to Mainpage.xaml page.</p>
  
  <p>Is there any best way to achieve this?</p>
