Abstract: The invention permits assembly of Web pages for display, to include text elements received from discrete network locations, and permits independent update of individual text elements of a Web page without reassembling the entire Web page, and permits independent update of all types of page elements without a client side agent other than a browser. In one aspect of the invention, a browser at a client device updates the display of a Web page containing at least one first element by transmitting a request to a server for a second element that is related to the first element, receiving the second element, and then displaying the second element with the Web page, without reassembling the Web page. In another aspect of the invention, the transmitting, receiving, and displaying are accomplished without a client side agent other than the browser.

Abstract: The present invention permits textual data to be exchanged between a Web page displayed in a standard Microsoft Web browser window and a server, utilizing a non-persistent HTTP connection. Traditionally, each time textual data is received to the displayed Web page a record is added to the history list. This is problematic as it clutters the history list, compromises the functionality of the browser “Back” and “Forward” buttons, and results in undesirable server operations to be executed. The present invention utilizes several methods for loading textual data to a displayed Web page, without adding a URL to the history list. In one aspect of the invention, a <xml> element is used to transmit a HTTP request for new data and receive the HTTP response. The present invention can be used to build a lightweight Web page that offers real-time data and interactivity.

Abstract: The present invention provides a system and method for retrieving and editing the data structure of a HTML UI Control, such as a treeview. The system and method have the capability to synchronize the data structure of a displayed HTML UI Control in a Web page with its corresponding data structure stored in an information system at a server, without refreshing said Web page. The present invention utilizes JavaScript to temporarily store the data structure of a displayed HTML UI Control. The JavaScript also has the capability to search and modify a corresponding information system at a server. One way to achieve this capability is by utilizing a browser-based Remote Procedure Call (RPC) and specialized business logic at the server to carry out server-side tasks on said information system.
