title: infinite jQuery cookie
body: <p>I plan to use some music on my site, but before I make it autoplay for each visitor, I would like to have either an alert pop up immediately, asking if they would like the music to play, or a nice little tooltip of some sort to present a message stating that you can check whether or not you would like the music.</p>
  
  <p>So, I know I can set a cookie via the <a href="http://plugins.jquery.com/project/cookie" rel="nofollow noreferrer">cookie plugin</a> but I was wondering if I could set the cookie's time to infinite, in other words, never to delete it, unless the end-user deletes all of their cookies, or the specific one for my site.</p>
  
  <p>Is this not considered a valid use of cookies?  If not, for a task like this, what should time do you suggest I set it to?</p>
