// The UAgentInfo class encapsulates information about

//   a browser's connection to your web site. 

//   The object's detection methods return booleans: true or false.

public class UAgentInfo

{

   //Stores some info about the browser and device.

   private String userAgent;

   //Stores info about what content formats the browser can display.

   private String httpAccept; 

   // A long list of strings which provide clues 

   //   about devices and capabilities.

   public static final String deviceIphone = "iphone";

   // [ SNIP! Other variables snipped out ]

   //The constructor. Initializes several default variables.

   public UAgentInfo(String userAgent, String httpAccept) {

            this.userAgent = userAgent.toLowerCase();

        if (httpAccept != null) {

            this.httpAccept = httpAccept.toLowerCase();
