问题
One of my client website is blocked in UAE, how can I redirect UAE users to another website if current website is blocked? for example: www.abc.com is accessible to the world but not UAE. I want UAE users to redirect to another website (i.e. www.xyz.com) if www.abc.com is blocked in their region.
