Why does URL Helper support unofficial HTTP header REFRESH?

Which begs the question: which browser was being used on this client's network? Or, in case of a corporate network, which security measures (reverse proxies, L7 load balancers, application level firewalls) were in place that could possibly interfere with 'non-standard' HTTP headers?[/quote]

The browsers in use were IE 8 and FF 3.6. I know this for a fact because I brought in my laptop to demo the latest version and both the stakeholders and myself stared at a blank screen waiting on the application to load. A little embarrassing...but that's just par for the course when it comes to a demo.

I resolved that situation by loading XAMMP and demoing locally.

I don't know much about the corporate network where the issue happened but I will find out what security they've implemented and let you know. I'm very curious myself because it seems like such an odd thing to filter out.

Great explanation btw! Thanks for the quick reply.
