If the files reside on the same server or domain then yes.
Otherwise, you will not be able to do so.

You would need to pass it on the URL

You should check the Referrer is null before continuing. Pages that don't have referrer will throw this error. Do a null check before you access ToString()

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Benefit of make the business layer class as sealed class

I set all my business layer classes as sealed class. I did like this because I read from somewhere that this will improve the performance. Is it true?

Thanks and Regards,

I set the class as sealed class when I want to prevent derivation.. That's all. I never heard that the sealed class is better than the normal class..

A sealed class cannot be used as a base class. For this reason, it cannot also be an abstract class. Sealed classes are primarily used to prevent derivation. Because they can never be used as a base class, some run-time optimizations can make calling sealed class members slightly faster.

I copied the above sentance from MSDN 2005
