browser's back button (or delete) to go back in history to your original
index you will not see the new data.
To demonstrate this just use:
*1> rails new demonstrate
2> cd demonstrate
3> rails scaffold User name:string
4> rake db:create
5> rake db:migrate
6> rails server*
Then in your browser go to *localhost:3000/users* and create a new user.
Then just use the browser's* *history to go back to the view of the (empty)
index at *localhost:3000/users* - you'll notice it's still empty.
If instead of the browser's history you use the *Back* link provided on the
page displayed after the successful creation of the new user, you'll see
the new entry displayed in the index.
Also, if you start another browser (say Safari if you're currently using
Firefox) on your local system and point it at *localhost:3000/users* Safari
will not track changes you make in Firefox even if you use the *Bake* link
provided by rails and get your Firefox index refreshed.
