Abstract

The present invention is an applet server which accepts requests for applets from client computers. A request specifies the format in which an applet is to be delivered to the requesting client computer. The applet server has a cache which it uses to store applets for distribution to client computers. If the specified form of the requested applet is available in the cache, the applet server transmits the applet to the requesting client. If the applet is not available in the cache, the server will attempt to build the applet from local resources (program code modules and compilers) and transformer programs (verifiers and optimizers). If the applet server is able to build the requested applet, it will then transmit the applet to the requesting client computer. If the applet server is unable to build the requested applet, it will pass the request to another applet server on the network for fulfillment of the request.

7. The method of claim 1 wherein transforming further comprises execution of the generated form.

8. The method of claim 1 wherein transforming further comprises verification of the generated form.

9. The method of claim 1 wherein transforming further comprises optimization of the generated form.

10. The method of claim 1 wherein the transformed form of the application is sent to the client computer in an HTTP response.

11. A method operating on a computer system, having a client computer and a server computer, for managing requests to the server computer, the method comprising:

at the server computer, receiving a request from the client computer, the request identifying an application and identifying a form of the application; and

in response to receiving the request;

compiling the application into a compiled form;

transforming the compiled application into a transformed form of the compiled form of the application, wherein transforming comprises execution and compression of the compiled form; and

sending the transformed form of the application to the client computer.

12. The method of claim 11 wherein the identified form of the application is specified using a Universal Resource Locator.

13. The method of claim 11 wherein the identified form of the application is specified using a cookie.

14. The method of claim 11 wherein the identified form of the application is specified in a HTTP header.

15. The method of claim 11 wherein the identified form of the application is a web page.

16. The method of claim 11 Wherein the identified form of the application is a portion of a web page.

17. The method of claim 11 wherein transforming further comprises verification of the compiled form.

18. The method of claim 11 wherein transforming further comprises optimization of the compiled form.

19. The method of claim 11 wherein the transformed form of the application is sent to the client computer in an HTTP response.

20. The method of claim 11, further comprising:

storing a plurality of available forms of the application;

the server, in response to receiving the request, determining if the identified form of the application is one of the stored plurality of available forms of the application; and

if the identified form of the application is one of the stored plurality of available forms, sending the identified form of the application to the client computer without compiling and transforming.

21. The method of claim 11, further comprising:

storing a plurality of available forms of the application;

the server, in response to receiving the request, determining if the identified form of the application is one of the stored plurality of available forms of the application; and

if the identified form of the application is one of the stored plurality of available forms, sending the identified form of the application to the client computer without compiling.

22. A method operating on a computer system, having a client computer and a server computer, for generating an application in response to a request by the client computer wherein each request for an application specifies one form of the application out of a plurality of forms of the application, comprising;

receiving on the server computer a request from the client computer for an application in a specified form from a plurality of available forms;

compiling and compressing the application to thereby generate the specified form; and

transmitting the generated application in the specified form to the client computer.

23. The method of claim 22 wherein the specified form of the application is specified using a Universal Resource Locator.

24. The method of claim 22 wherein the specified form of the application is specified using a cookie.

25. The method of claim 22 wherein the specified form of the application is specified in a HTTP header.

26. The method of claim 22 wherein the specified form of the application requested is a web page.

27. The method of claim 22 wherein the specified form of the application requested is a portion of a web page.

28. The method of claim 22 wherein the specified form of the application is transmitted to the client computer in an HTTP response.
