title: getting the flash hash to persist through redirects
body: <p>My basic use case is do some processing, set <code>flash[:notice]</code>, and then redirect to a new page. From what I can tell, redirects reset the flash tag (please correct me if I'm wrong). Is there a way to gain persistence? Using sessions isn't an option, and I have hacked around the problem using cookies, but I think there's got to be a better way.</p>
