Internet Explorer Has Native Support for Persistence and Saving Session Across Page Loads Without Cookies
>Brad Neuberg has written up a lot on the state of state in the browser :)
This is a mini-tutorial on saving state across page loads on the client side, without using cookies so as to save large amounts of data beyond cookies size limits.
He discusses two ways to deal with session state in the client:
- Method number one is to use an iframe in some special ways. First, this iframe must exist on page load, Then, whenever you wish to record state that you want to save, you must write that state into the iframe
How the heck did I miss the existence of non-cookie persistence features in Internet Explorer since IE 5? This is from MSDN:
“Persistence enables authors to specify an object to persist on the client during the current and later sessions using Dynamic HTML (DHTML) behaviors. Persistence allows Microsoft Internet Explorer 5 and later to retain Web page information, styles, variables, and state. For example, a collapsible list of links within a table of contents can remain expanded to the user’s choice upon leaving and later returning to the page. Or, a search engine query form can retain the last-used searchstring.
