I have always had a problem with long forms and having user info expire before the forms were filled. I have done long forms in sections with a submit for every page. I have done timed javascripts that calls a pop-up after 25 minutes telling the user to save and continue. Yada Yada Yada. I am in the middle of putting together a very long form for a client and decided to try a different approach. I load a taf into an iframe with height and width attributes set to 1. The taf doesn't return anything, it's just a header with a meta-refresh every 25 minutes (1500 seconds). Now call me dumb, but this works perfectly, as far as I can tell. I've tested it on many forms, forums, in-house blogs, etc., and I cannot get it to break. Every refresh refreshes the variables and holds onto all the user info. A really simple solution to what I thought was a vexing problem. I just updated a bunch of stuff by adding the iframe at the bottom of a bunch of form pages. I cannot find any drawbacks to this... I hope I am not missing something.
