title: How to preserve "post data" on redirect
body: <p>I want to redirect a post from /mynode to /eng/mynode/ and preserve form data.
  I've tried "Server.Transfer" but I get an error saying "Error executing child request for /en/mynode".</p>
  
  <p>I would like to implement this in a general fashion, for example in OnPreInit() method of base page.</p>
  
  <p>Do you see any other options?</p>
  
  <p>P.S. When you use Server.Transfer, "the page transferred to should be another .aspx page. For instance, a transfer to an .asp or .asmx page is not valid". See <a href="http://msdn.microsoft.com/en-us/library/y4k58xk7%28v=vs.110%29.aspx" rel="nofollow">source</a>. </p>
