There will be times when you want finer control of the display on the client. The best example of this would be with logos.

That is where the M-Business Client headers come in. As you already know, when a browser accesses your Web server, it sends across several headers in the HTTP page request. These are informational headers telling your server a little about the browser; what type of browser it is, what host it thinks it is connecting to, the language the client prefers, and other parameters as follows: all of which can be used to customize content.
