As you might know there are an incredible amount of advent calendar blogs out at the moment each delivering one cool article for each day of December until Christmas.
Today (6/12/11) two calendar blogs delivered an article of mine talking about the benefits of using local storage in browsers and how to implement it.
In essence, the article explains why it is a good idea to use local storage, explains how to use it, how to work around the issue that local storage can only store strings and gives example code on how to speed up web service use by caching information client-side much like you would do it on a server.
Have a read and go speed up your own solutions by using what browsers provide you these days.
