Create New Excel File Using Vb

I'm still puzzled though. My understanding is that Ajax is just a way of forming and sending a request. Once it's sent, that's it. The server forms the response and sends it back to the browser.

Is there something unique, such as a header, in the response that says 'this response is intended for the Javascript engine, not the HTTP rendering engine'? There must be some way that the browser knows the difference. I know I'm getting into technical details that aren't really pertinent, but I'm one of those people that has to understand how everything works. Maybe there is a technical specification on Javascript that I need to read?
