title: How to set and use a variable with iframes?
body: <p>I've written a little webpage that enables split-screen viewing in any iframe-enabled browser.  It has back buttons, forward buttons, home buttons, and links to Bing and Google.  What I'm trying to figure out is how to store a homepage value input by the user.  I can't for the life of me figure out how to do this; I've tried several tutorials for setting variables in cookies. (Cookies are the right way to do that, right?)</p>
  
  <p><a href="http://twobrowse.cogizio.org/" rel="nofollow">This</a> is the page so far.  I want to remove the Bing and Google buttons and replace them both with a "Set as Home" button to the right of the Go button.  What javascript, CSS, and HTML magic am I missing here?</p>
  
  <p>The person whose work gets this done will be credited on the page, both on the iframe's home page and in the main page's source code.</p>
