How to declare a variable in the global scope?

[Guest]

You can have a base page class that all of your pages inherit from and
retrieve all of your variables from the web.config file. This eliminates
using Application and Cache variables which are (InProc)ess variables. They
will be available to all of your pages. You may also want to create a base
user control from which all your user controls can inherit from. Finally, in
web.config, you can modify the <pages> node to set the base page and user
control that all your pages will inherit from.

why don't you use some application object in ASP.NET for accessing that
variable globally.
