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.
