For long and indeterminate page processing, like connecting with a credit card payment gateway or calculating pi to thousands of significant digits, what is your preferred method for displaying ³please wait²?
I see two techniques: 1. Use Javascript upon form submission to display the ³please wait² message 2. Echo a ³please wait² page from the server and then do a 302 redirect upon completion of the scrpt. Issues: 1. Not everyone uses JavaScript 2. Can you issue a header redirect after echoing a ³please wait² message. I though headers need to be sent first. Is a 302 header redirect an exception? Cliff
