I have a UIWebview. Let's say I open google in that view and then I press the back button and come back to Webview page again. Is it possible to see google (already opened) instead of loading that page again?

I also edited your tags for "caching"; you can check out other questions under that tag – dgund Jul 21 '12 at 13:49

Yes indeed, it is called caching. It basically saves the page in memory so that it can be called later without loading. The only major problem is that if your "cache" (save) a page, if the page is updated on the internet it will not be updated in your app until the page is refreshed and loaded.
There is a lot of information on caching for iOS, just search on the Internet. A helpful link I found is this Stackoverflow question which shows you how to cache content.
