Abstract

A method for optimally maintaining the execution of a first application, wherein the first application is further configured to received a set of sequential data elements from a second application, and the set of sequential data elements further includes a first data element and a second data element. The method includes establishing a connection between the first application and the second application. The method further includes transmitting a request to send the set of sequential data elements; receiving the first data element from the second application; and determining if the connection is still active. If not, the method also includes reestablishing the connection; transmitting a request to the second application to resend the first data element; receiving the first data element; and, if necessary, receiving the second data element.

Claims

1. A method of maintaining the execution of a first application, wherein said first application is further configured to received a set of sequential data elements from a second application, and said set of sequential data elements further includes a first data element and a second data element, comprising:

establishing a connection between said first application and said second application;

transmitting a request to send said set of sequential data elements;

receiving said first data element from said second application;

determining if said connection is still active; and

if not,

reestablishing said connection;

transmitting a request to said second application to resend said first data element;

receiving said first data element; and

, if necessary,

receiving said second data element.

2. The method of claim 1, further comprising a third application coupled to said second application, wherein in said establishing step, said connection is established between said first application and said third application.

3. The method of claim 2, wherein after said receiving step, said second application sends said set of sequential data elements to said third application.

4. The method of claim 1, wherein said first application is comprised of a first web browser, and said second application is comprised of a web server, wherein said connection is established by transmitting said set of data elements from said web server to said web browser.

5. The method of claim 4, wherein said first application is further comprised of a second web browser coupled to said first web browser, wherein said second web browser can render said set of data elements.

6. The method of claim 1, wherein said set of data elements further comprises DHTML.

7. The method of claim 1, wherein said set of data elements further comprises XML.

8. The method of claim 1, wherein said set of data elements further comprises active data.

9. The method of claim 1, wherein said set connection further comprises a packet network.

10. The method of claim 1, wherein said set connection further comprises a wireless network.

15. The apparatus of claim 4, wherein said first application is further comprised of a second web browser coupled to said first web browser, wherein said second web browser can render said set of data elements.

11. An apparatus for maintaining the execution of a first application, wherein said first application is further configured to received a set of sequential data elements from a second application, and said set of sequential data elements further includes a first data element and a second data element, comprising:

a means for establishing a connection between said first application and said second application;

a means for transmitting a request to send said set of sequential data elements;

a means for receiving said first data element from said second application;

a means for determining if said connection is still active; and

if not,

a means for reestablishing said connection;

a means for transmitting a request to said second application to resend said first data element;

a means for receiving said first data element; and

, if necessary,

a means for receiving said second data element.

12. The apparatus of claim 11, further comprising a third application coupled to said second application, wherein in said establishing step, said connection is established between said first application and said third application.

13. The apparatus of claim 12, wherein after said receiving step, said second application sends said set of sequential data elements to said third application.

14. The apparatus of claim 11, wherein said first application is comprised of a first web browser, and said second application is comprised of a web server, wherein said connection is established by transmitting said set of data elements from said web server to said web browser.

16. The apparatus of claim 11, wherein said set of data elements further comprises DHTML.

17. The apparatus of claim 11, wherein said set of data elements further comprises XML.

18. The apparatus of claim 11, wherein said set of data elements further comprises active data.

19. The apparatus of claim 11, wherein said set connection further comprises a packet network.

20. The apparatus of claim 11, wherein said set connection further comprises a wireless network.
