Go back online

Some websites change their content time to time. We may not able to find their past content at present. So here is a solution.
For instance, I browse a website, which removes its past content older than 90 days, as it updates its content regularly. But once I required its past content. Then I found a solution.

http://archive.org archives the online information (content) for the future. So all major changes on the websites are still available although it is removed from the original sourse.



It has helped me a lot.
