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.
Claims15
A method for providing bidirectional communication between a user agent and a Web application server over a network, comprising the steps of:
- providing a user agent and an application server, said user agent and said application server communicating via a hypertext transfer (HTTP) protocol, each of said user agent and said application server executing within a computer;
- providing a server procedure configured to operate in association with said application server and associating a procedure identifier with said server procedure, said procedure identifier identifying said server procedure, said server procedure executing within a computer;
- constructing by said user agent, a hypertext transfer protocol (HTTP) uniform resource identifier (URI) that includes at least said procedure identifier and a time identifier, said time identifier identifying a time of occurrence of said event and where said uniform resource identifier (URI) is constructed by said user agent in response to a user agent detectable event and where said procedure identifier is selected in association with said event;
- transmitting by said user agent to said application server, a first communication including a hypertext transfer protocol (HTTP) REQUEST message, said (HTTP) REQUEST message including said uniform resource identifier (URI);
- receiving and processing by said application server, said (HTTP) REQUEST message, said processing including the execution of said server procedure identified by said procedure identifier, constructing by said server procedure, a second communication including information responding to said first communication, said information stored within a portion of an HTTP RESPONSE message and where said portion is located outside of a body field of said HTTP RESPONSE message;
- and
- transmitting by said application server to said user agent, said second communication.

A Web server providing bi-directional communication with a user agent over a network comprising:
- an application server including at least one server procedure configured to operate in association with said application server, said application server configured to communicate with a user agent via a hypertext transfer (HTTP) protocol, each of said application server, said server procedure and said user agent executing on a computer;
- said application server configured for receiving and processing a first communication including an (HTTP) REQUEST message from said user agent, said processing including the execution of said server procedure identified by a procedure identifier included within said (HTTP) REQUEST message, said (HTTP) REQUEST message including a hypertext transfer protocol (HTTP) uniform resource identifier (URI) that includes at least said procedure identifier and a time identifier, said time identifier identifying a time of occurrence of said event and where said uniform resource identifier (URI) is constructed by said user agent in response to a user agent detectable event and where said procedure identifier is selected in association with said event;
- said server procedure configured for constructing a second communication including information responding to said first communication, said information stored within a portion of an HTTP RESPONSE message and where said portion is located outside of a body field of said HTTP RESPONSE message;
- and
- wherein said application server is configured to transmit to said user agent, said second communication.

A Web client providing bi-directional communication with a Web server comprising:
- a user agent configured for communicating with an application server, said application server including a server procedure configured to operate in association with said application server, said server procedure identified by a procedure identifier, said application server being configured to communicate with a user agent via a hypertext transfer (HTTP) protocol, each of said user agent, said application server and said server procedure executing within a computer;
- said user agent configured for constructing a hypertext transfer protocol (HTTP) uniform resource identifier (URI) that includes said procedure identifier and a time identifier, said time identifier identifying a time of occurrence of said event and where said uniform resource identifier (URI) is constructed by said user agent in response to a user agent detectable event and where said procedure identifier is selected in association with said event;
- and
- said user agent is configured for transmitting to said application server, a first communication including a hypertext transfer protocol (HTTP) REQUEST message, said (HTTP) REQUEST message including a uniform resource identifier (URI) including said procedure identifier, and configured for receiving a second communication including information responding to said first communication, said information stored within a portion of an HTTP RESPONSE message and where said portion is located outside of a body field of said HTTP RESPONSE message;
- and configured for extracting and processing said information.
