Frames and Cookies (how to)

Internet Explorer (or any other Browser) may prevent the use of cookies (and consequently sessions) when HTML frames point to files located in different servers. A possible solution to that "error" involves setting up a proper Privacy Policy (see "Platform for Privacy Preferences Project - P3P" link bellow). You can do that by sending the following HTTP header data to the client system:

P3P: CP="CAO PSA OUR"

Here is the code in PHP:
<?php header('P3P: CP="CAO PSA OUR"'); ?>

(From: The Contender at http://transcripts.cnn.com/TRANSCRIPTS/0102/13/i_ins.00.html ) Mark Darcy : I won't dignify that question with an answer. (From: Bridget Jones: The Edge of Reason at http://www.script-o-rama.com/movie_scripts/b/bridget-jones-the-edge-of-reason-script.html ) Sometimes, just by replying, we validate the question been posed. There are times when keeping it silent might be the best response of all. Whether or not we have the right answer . And, as always, not to answer is an answer. Carpe Diem,
