Description Author  

This class parses user agent identifier strings from browsers used by mobile devices to extract relevant information.

It recognizes many of the current mobile user agent identifier strings and processes them to extract their basic constituent parts, the most important being the mobile device vendor and model.

An useful application of this class is to use the extracted information to lookup vendor and model specific device characteristics in a database, or to detect if the visiting browser uses a certain type of mobile device.

Of course you could use user agent profiles for this, but not all mobile phones have (valid) user agent profiles, especially the older types of mobile phones.

This class was already verified to work correctly with over 2000 user agent strings.

The possibilities of mobile devices like cellular phones and palmtops vary a lot depending on the type of device, brand and model characteristics.

To take advantage of the possibilities of each type of device it is necessary to know which are the supported capabilities.

This class is capable of parsing the User-Agent identification string sent by the device browser application to the Web server. Then it extracts the relevant details that can be used to cross-check a database of device specific characteristics supplied by their vendors.

With this information it is possible to determine which capabilities can be used to deliver content or provide services to each type of mobile device that accesses a Web site.
