Chapter 28. The System.Web.Mobile Namespace

Version 1.1 of the .NET Framework incorporates support for
mobile devices that have a wide range of
abilitities, including Pocket PCs, PDAs, and Internet-enabled
cellphones. Some devices expect Wireless Markup Language (WML), while
others support compact HTML (cHTML) or ordinary HTML content.
Fortunately, ASP.NET embraces this diversity with intelligent mobile
controls that can render the correct output based on information
supplied by the client browser.

The System.Web.Mobile
namespace includes the core functionality required for mobile web
applications, including classes that process errors, perform forms
authententication, and retrieve the capabilities of the client
device. Several of these classes are used internally by ASP.NET,
while others (namely the MobileCapabilities and
MobileFormsAuthentication classes) are accessed
directly in your code. Figure 28-1 shows the types
in this namespace

The System.Web.Mobile namespace includes two key
classes for the mobile ASP.NET developer. The
MobileFormsAuthentication class allows you to
retrieve fine-grained information about the requirements and
abilities of a client device. The
MobileFormsAuthentication class provides shared
helper methods that allow you to use forms authentication with
devices that don't support cookies by embedding
encrypted authentication information into the URL.
