A very strange phenomenon I came across while developing web application for a customer.
A Jpeg formatted picture wasn’t shown on IE8 browsers, while shown on others (Firefox 5, Chrome 12, IE9). ...
A common and very misleading http error is the status with code 404.2 .
It is misleading because it belongs to the 404 family which may indicate
that the resource was not found, however this error indicates that the
server has blocked our request by it’s lockdown policy.
