title: Suppress Safari can't open the page because the address is invalid? custom app launch
body: <p>I'm launching a custom app from a web browser on the iphone. </p>
  
  <p>If the app is not installed I am redirecting to a web page on the website.</p>
  
  <p>If it is installed it goes to a specific page on the app</p>
  
  <p>This all works as expected except for about 1/2 a second safari displays a modal window saying the following</p>
  
  <p>Cannot Open Page
  Safari cannot open the page because the address is invalid. </p>
  
  <p>I know the address is invalid and I would like to know if its possible to suppress the error message in safari.</p>
  
  <p>Thanks</p>
