Abstract

A method, system and computer program product for adaptive messaging in a computer network having a client machine and at least one server. Typically, the client machine is located behind a firewall. According to the invention, a communication from the server to the client may be “repackaged” in an e-mail message in the event a point-to-point connection between the server and the client cannot be established due to the firewall or some other network constraint. The client typically communicates with the server by the point-to-point connection. The technique is especially useful in an automated diagnostic method wherein users of client machines interact with a diagnostic system located at a server.

Claims

1. An electronic communications method between first and second entities over a computer network having an e-mail subsystem, comprising the steps of:

upon a connection request from the first entity to the second entity, determining whether a connection can be established between the first and second entities using a first connection preference;

if the connection cannot be established using the first connection preference, opening a connection to the e-mail subsystem;

encapsulating a communication in an e-mail message; and

transmitting the e-mail message, together with the encapsulated communication, from the first entity to the second entity via the e-mail subsystem.

2. The method as described in claim 1 wherein the first and second entities are separated by a firewall.

3. The method as described in claim 1 wherein the first and second entities communicate over a network that does not adequate support the first connection preference.

4. The method as described in claim 3 wherein the first connection preference is a point-to-point connection.

5. The method as described in claim 1 further including the step of having the second entity validate and process the e-mail message to obtain the communication.

6. The method as described in claim 5 further including the step of transmitting a response to the communication from the second entity to the first entity.

7. The method as described in claim 6 wherein the response is transmitted using a connection conforming to the first connection preference.

8. The method as described in claim 1 wherein the first and second entities are computers.

9. The method as described in claim 8 wherein the first entity is a client machine having a Web browser, and the second entity is Web server.

10. An electronic communications method between a server and a client over a computer network having an e-mail subsystem, the client located behind a firewall, comprising the steps of:

upon a connection request from the server to the client, determining whether a point-to-point connection can be established between the server and the client;

if the connection cannot be established using the point-to-point connection, encapsulating a given communication in an e-mail message;

delivering the e-mail message, together with the given communication, from the server to the client via the e-mail subsystem; and

sending a response to the communication from the client to the server via a point-to-point connection.

11. The method as described in claim 10 wherein the computer network is the public Internet and the client includes a Web browser.

12. The method as described in claim 10 wherein the computer network is an intranet and the client includes a Web browser.

13. The method as described in claim 10 further including the step of validating and outputting the communication to a recipient at the client prior to the step of sending the response.

14. A computer program product in a computer-readable medium for facilitating electronic communications between a server and a client in a computer network having an e-mail system, the computer program product executable in the server and comprising:

means operative upon a connection request from the server to the client for determining whether a point-to-point connection can be established between the server and the client;

means responsive to the determining means for opening a connection to the e-mail system if the point-to-point connection cannot be established; and

means for associating to an e-mail message a given communication to be delivered from the server to the client.

15. The computer program product as described in claim 14 wherein the means for associating attaches the given communication to the e-mail message.

16. The computer program product as described in claim 14 wherein the server is a Web server and the computer network is the public Internet.
