Abstract
A method and an apparatus for providing bidirectional communication between a user agent and an Internet Web server. Some applications include user agent initiated on demand access to Web content without requiring a Web page reload, updating of shopping cart information, extension of displayed product information and tracking of user interaction history. Web content can be accessed in response to a user agent detectable event, including such as the selection of a text field or a button. This approach enables user agent resident JAVA script to access and process Web content before it is rendered to a user.
