texte = Some browsers do not cache when they should... the best workaround is to make your forms submit to themselves and write custom code (or tweak someone elses - see archives) which does error checking on that same page and displays any problems if there are any... if there are no problems, then the page can silently redirect on to the next page (the page you really wanted the form submit to go to in the first place). Sorry to say this is going to be some work, but at this point it appears there is no better alternative. On the up side - once you manage this new type of technique, you can keep using it and no longer worry so much how well (or not) the latest browsers are handling caching.ask if something hear was not clear-JohnChristopher Mackay wrote:> Hi, > > My forms are now in pretty good shape, but not perfect.
