WAP is the Web protocol for delivering content to wireless devices, like cellular telephones or palmtop devices. Usually this content is retrieved on demand when the users access the network with such devices. The users only know about new content when they intentionally access the Web.
WAP Push is a way to warn users about updated content. It uses SMS messages to inform the URLs of content of interest that was updated, so the users do not have to keep polling the Web using their WAP devices to be notified when there is new content of their interest.
This class provides an interface for sending WAP Push SMS messages using the Clickatell services.
