title: Response.Redirect to a Clickonce not working if done during postback
body: <p>Very odd situation here. I'm trying to launch a .application file using Response.Redirect. In the Page_Load event, if I check that it is a postback, it doesn't launch (it does otherwise). If I redirect to another page in postback, it works fine.</p>
  
  <p>The reason I'm launching in postback is I'm checking that .Net is installed by grabbing navigator.useragent in javascript and sending that back to asp.net via a postback (actually a form[0].submit()) to see if the .Net framework is installed.</p>
