### Using the <postfield> Tag

The Web browser interface supports the <postfield> tag. The <postfield> tag allows an application to set a name/value pair that can be sent to the source of the request. The name is set by the name attribute and must be a valid WML variable name. The value is set by the value attribute. A <go> element can contain one or more <postfield> tags. Postfield tags must be sent if HTTP POST method is used.

NOTE: For more information on the <postfield> tag, see Chapter 7: Web Browser for 9620 and 9630 IP Telephones.
