Solution for no vibration on iPhone 3GS

April 23rd, 2010

Anyway, if you find that the vibrate keeps going off again, simply download one of those free vibration apps.

P3P fix for Internet Explorer to access cross domain cookie in iframe

Google says that all you need to do to get this working is setup a P3P Cookie Privacy policy according to P3P Specifications. Most results also say that all you need is to setup the P3P policy in the header. Such as in VB

Code

HttpContext.Current.Response.AddHeader("P3P", "CP=""CAO PSA OUR""")

OR in PHP

PHP

<?php header('P3P: CP="CAO PSA OUR"'); ?>
