Filed:

Appl. No.:

09/268068

Inventors:

Rodger D. Erickson - St. Louis MO
Ronald D. Sanders - Spokane WA

Assignee:

Wall Data Incorporated - Kirkland WA

International Classification:

G06F 1300

US Classification:

709228, 709217, 709236, 709313

Abstract:

A method and system for providing a persistent HTTP tunnel for a connection-oriented protocol between a client and a Web server. A data message complying with the connection-oriented protocol is generated and embedded into a chunked data message in compliance with a chunking option for the HTTP. The chunked data message is transmitted between a client and a Web server. Upon receiving any chunked data message at the Web server, the Web server parses the chunked data message and delivers the data message to a host system. Upon receiving any chunked data message at the client, the client parses the chunked data message and delivers the data message to a terminal emulator running on the client. This allows a terminal session to be supported by a real-time bi-directional persistent connection with the host system. The bi-directional persistent connection allows interleaving of the chunked data messages from the Web client with the chunked data messages on the Web server on the persistent HTTP tunnel.

Abstract:

A method and system for caching content, such as content requested from a server on the World Wide Web. Requests for dynamic content are forwarded directly to a content server to avoid caching data that might only be used once. Requests for static content are forwarded to a hot or a regular cache depending on the frequency at which the content is requested. When a hot cache does not contain the content, it forwards the request to the forwarder which then forwards the request to a regular cache. When the regular cache does not contain the content, it requests the content from the forwarder which then forwards the request to a content server. There may be more than two layers of cache.
