What is the Microbrowser
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.
