title: Aspx file in two master pages
body: <p>I have a page on a website that uses a master page and a child page. I would like to use the child page to create a new page on the website, but with a different master page.</p>
  
  <p>Is it possible to do this without duplicating the code for the child page? 
  To make it clearer I have also added a <a href="http://i.imgur.com/DhPcNOS.png" rel="nofollow">link</a> to a picture of the layouts used for the two pages.</p>
  
  <p>In the picture, both children use the same code.</p>
  
  <p>Edit: I have also thought about using a control for this, but I am not sure if this is the proper solution. The child page is pretty big and complex and also uses a lot of JavaScript.</p>
