Method of accessing information on a host computer from a client computer
First Claim
1. A system for facilitating information transfer between a host computer and a client computer via a server computer, comprising:
- a host computer comprising a memory within which a presentation space buffer storing computer display information is configured and a communications interface enabling information exchanges using data streams, including transmission of the presentation space buffer as a presentation space data stream;
a client computer comprising a web browser application displaying a markup language document and forwarding user inputs; and
a server computer topologically intermediate to the host computer and the client computer and comprising;
a server application framework comprising a display control interfacing to the host computer via a communications medium over which data streams are exchanged, including the transmitted presentation space data stream, and a host extension converting the transmitted presentation space data stream into a markup language document having instructions that identify position information for a cursor on a Web page and for modifying the presentation space buffer in the host; and
a web server application interfacing to the client computer via a network medium over which the markup language document is served and the forwarded user inputs received.

Abstract
A method and apparatus for accessing information on a host computer 106 from a client computer 104 utilizing an intermediate server computer 108 that is connected to the client computer by a network. The host computer transmits a presentation space data stream representing a host screen to the server computer. The server computer creates an HTML document based on the information received from the host computer and transmits the HTML document to the client computer. The client computer creates a Web page based on the HTML document. The Web page includes fields and controls that implement the functionality of the host screens while presenting an improved user interface. A user can create HTML templates that substitute for the automatically created HTML documents for any one or more of the host screens. The server computer inserts session identifiers within the URLs that are contained in the HTML documents, and uses the session identifiers to maintain separate connections between multiple host computers and a single client computer.

19. A method for facilitating information transfer between a host computer and a client computer via a server computer topologically intermediate to the host computer and the client computer, comprising:
-
configuring a presentation space buffer within a memory of the host computer and storing computer display information into the presentation space buffer; exchanging information using data streams, including transmission of the presentation space buffer as a presentation space data stream, via a communications interface of the host computer; displaying a markup language document and forwarding user inputs using a web browser application of the client computer; and interfacing to the host computer via a communications medium over which data streams are exchanged, including the transmitted presentation space data stream, using a display control of a server application framework of the server computer; converting the transmitted presentation space data stream into a markup language document using a host extension of the server application framework of the server computer, the markup language document having instructions that identify position information for a cursor on a Web page and for modifying the presentation space buffer in the host; and interfacing to the client computer via a network medium over which the markup language document is served and the forwarded user inputs received using a web server application of the servor computer. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
