I am using an iframe to hold a file kept on our server. Clients fill out a form that updates this file. When a button is pressed, the new file fills the iframe. This works great for most of my clients, but occasionally a cached version of the file is used to fill the iframe.
Is there a way to make the clients computer pull the image off of the server and not use a cached version of the file?
(Just for the record, I don't have access to any of the client computer settings.)
I would appreciate any help or suggestions.
Thanks,
Lester
