Abstract: A method and system for browser notification of a change in browser information content and update of the browser information content. A browser establishes an http connection with a server and loads a web page with information content. At the same time, the server and client also establish a socket connection to pass messages from the server to the client over the socket connection. When the server determines that browser content needs update or has changed, the server sends a change notice message over the socket connection. Upon browser receipt of the change notice message, the browser initiates an refreshes the information content over the http connection.

Abstract: A method and system for RAM data cache of information maintained in an SQL type of database. A subset of the SQL data, in the form of a lite cache is extracted and stored in RAM. The lite cache includes a record ID and one variable, although the SQL database includes a plurality of variables associated with the record ID. Information query is directed first to the cache and if the cache exists, responses are returned from the cache rather than from the SQL database. Multiple lite cache are created with some initialized upon server load, and other initialized upon the first query. Update to the lite cache is provided on a periodic basis, or upon change in underlying data.
