Facing Great Difficulty in configuring my web app. Properly for a custom URL on my IIS --

Hi All.
My first post on this forum.

Actually I didn't even know that an complete IIS forum existed separately. I had originally posted my problem on another of the Microsoft forums. I am not typing the whole thing all over again hope you understand.
Please read it from here, everything written there ::

Can any of you tell me something about this please? How do I do it? I need some assistance on it, friends.

Thanks.
