Really Simple History is a lightweight JavaScript library for the management of bookmarking and browser history in Ajax/DHTML applications. RSH serializes application data in an internal JavaScript cache so that bookmarks and the back button can be used to return your application to an earlier state.

Originally developed by Brad Neuberg in 2005, RSH has won a large user base for its simplicity, ease of use and lack of dependency on any specific Ajax framework. It's written in plain old JavaScript and can be included on any site according to the terms of its BSD license.

In September 2007, Brian Dillard came on board as maintainer and ongoing code steward for the project. A new version, with support for additional modern browsers (IE7, Safari, Opera), was released as RSH 0.6 in late 2007.

RSH 0.8 is currently in development as of May 2009.
