Javascript/HTML Storage Options Under File Protocol (file://)

by

A buddy of mine at work helped me out with this problem by sharing his implementation of using window.name to store data across pages of a single window/session.

A similar implementation (and discussion around the method) can be found here: http://ajaxian.com/archives/whats-in-a-windowname

Preliminary tests I’ve been doing on this method look very promising. I tested this, under the file protocol (loading page from desktop, a.k.a. – “file:\”) on the following browsers. It worked on all of them!!

  • IE 6
  • IE 7
  • IE 8
  • IE 9
  • FF 3.6
  • FF 4
  • Chrome 11
  • Opera 10
  • Safari 4

I have not yet done any testing as to how much data you can store here, but the internets seem to agree on a value of 2 MB.
