development.
This chapter contains information on:

To develop an application that can run on the Microbrowser, refer to

your applications, refer to 

The Microbrowser is like any Web browser—Microsoft Internet Explorer and 

Firefox, for example—but supports only a subset of XHTML features. It can 

connect to Web servers hosted in the Internet or intranet and download 

XHTML pages. The Microbrowser supports a limited number of XHTML 1.0 

features—it does not have full Web browser functionality.
The Microbrowser downloads XHTML content from a Web server into the 

phone’s memory, then parses the content to identify XHTML tags and renders 

these tags onto the phone's graphic display. The appearance of the rendered 

page depends on the graphical capabilities and display size of the device on 

which the browser is running. Complicated pages should be avoided on 

devices with very small displays.
The Microbrowser does not support scripting (such as JavaScript). All actions 

on data entered into forms is processed by the server using POST or GET 

methods.
