Unsupported browser message not shown for BSP iView

Hello,

Portal version : EP7.0

For a BSP iView, I want to restrict that it should load only with IE browser. For all other browsers, it should show some "user-agent not supported" kind of message.

I have set following two properties for this iView: -

Supported User Agents: (MSIE, >-5.5, *)

Unsupported User Agents: (Netscape, *,*) (Mozilla, >-*. *)

It loads correctly from IE.

But when I access this iView from Chrome/Firefox, I see a blank screen.

Is it normal behavior? Why it isn't showing some standard message to let user know that this browser isn't supported?

Thanks & Regards,

Amey Mogare
