Small through-request data storage

Is there any solutions or practices of 开发者_如何学运维how to organize small local data storage to keep some data between requests (no cookies or another sending data to server)?

window.name can hold several MEGABYTES worth of string data. It must be used carefully though.

See: Using window.name as a local data cache in web browsers

Local Storage ability is included in HTMl5. Check out this link for more information (http://diveintohtml5.ep.io/storage.html). This will not work in older browsers.
