Now you want to do some update on newly created record, you might come back by Using BACK Button of browser. The moment you will click Back button, you will find following error message.

I have implemented and fixed this by two ways.
1.By using cookies(javaScript) : You can set cookies the way that the moment it goes to defaulter page it should redirect to some other page.
2.Delete History : After saving newly created record, user will go to next page, the moment user click Next Page, bu Using delete History u can delete defaulter page from cache.
Thanks
