iOS App - Refresh last webView on applicationDidBecomeActive
===

I have a single view iOS app, that contains a webView that displays my website.  When the app is returned to from multitasking (when it is brought back as the active app) I would like the webView to get the URL it is currently on, and refresh (or reload) that current page in the webView (I'm thinking using this method):

    - (void)applicationDidBecomeActive:(UIApplication *)application
    {
        NSLog(@"applicationDidBecomeActive");
    }
How would I do this? Do I need to subscribe to some sort of notification? Please help point me in the right direction, and provide some code.
