This is a nightmare. You will eventually miss a cache invalidation and break browser navigation or invalidate the cache so aggressively that TurboLinks is serving no purpose.

You don't need lots of negative testimonials to see that managing your own client side cache with JavaScript is a bad idea.

Haven't had any problems with this in 2 years in production. It also works fine for Basecamp.
