| # This is just an hint for a simple Redis caching "framework" using Sinatra | |
| # A friend of mine asked for something like that, after checking the first two gems realized there was | |
| # a lot of useless complexity (IMHO). That's the result. | |
| # | |
| # The use_cache parameter is useful if you want to cache only if the user is authenticated or | |
| # something like that, so you can do cache_url(ttl,User.logged_in?, ...) | |
