The invention relates to a method and apparatus for regenerating portions of the page that have changed and transmitting only those portions to the client for display. Executing only the necessary parts of the page generation code and transmitting only changes to the client improves the efficiency of using the resources of the network communication channel, the client node and the server node. Performing these operations only when required, when the data has changed, improves the efficiency of use even further. The invention also takes advantage of any portions of the page that are already on the client by reusing them and thus eliminates the need to regenerate or transmit those reusable portions. In one aspect, the invention relates to a method for incorporating a partial page into a transmitted page displayed on a client. The method includes displaying the transmitted page on a client, receiving by the client a regenerated portion of the transmitted page from a server and incorporating by the client the regenerated portion into the transmitted page displayed on the client. In one embodiment, the method includes receiving by the client a modification list from the server instructing the client on the incorporation of the regenerated page portion into the transmitted page. In another embodiment, the method includes receiving by the client additional code instructing the client on how to interpret commands contained in the modification list.

1. A method for selectively altering the display of page elements, said method comprising: a. receiving, at a client, a page dynamically generated by a plurality of code fragments executing on a server, comprising an executable function and a plurality of elements, each element generated by a code fragment of the plurality of code fragments and designated by an identifier;b. displaying, by the client in a web browser, the received page;c. executing, by the client in response to at least one user input, the executable function, the executable function sending a request to the server, the request initiating execution of a first code fragment of the plurality of code fragments to generate an updated element;d. receiving, by the client from the server, a response comprising the updated element and a modification list comprising an identifier identifying a first element in the page also generated by execution of the first code fragment,wherein a partial page regenerator executing on the server generates the modification list responsive to using a map of correspondences to identify elements in the page received by the client and updated elements generated by the same code fragments; ande. displaying, by the client in the web browser, an updated page incorporating the updated element by replacing the first element in the page with the updated element according to the modification list. 2. The method of claim 1, wherein the executable function comprises a Javascript function. 3. The method of claim 1 wherein the plurality of elements comprises a plurality of XML elements. 4. The method of claim 1 wherein step (c) further-comprises sending a request to a server, the request comprising the value of at least one user input. 5. The method of claim 1, wherein step (d) further comprises receiving, from the server, a response comprising a plurality of updated elements and a corresponding plurality of identifiers, each of the plurality of identifiers identifying an element in the page. 6. The method of claim 5, wherein step (e) further comprises displaying, in the web browser, an updated page comprising the page with each of the identified elements in the page replaced with a corresponding one of the plurality of updated elements. 7. The method of claim 1, wherein the partial page regenerator generates the modification list responsive to tracking values on the page previously received by the client and corresponding values that are modified by execution of the first code fragment. 8. The method of claim 1, wherein the page received by the client comprises a second element identified by a corresponding second identifier; andwherein the request sent to the server by the executable function further initiates execution of a second code fragment of the plurality of code fragments to generate a second updated element, the second updated element comprising the second element of the received page in a new location on the updated page; andwherein the modification list comprises the second identifier and the new location; andwherein displaying an updated page comprises moving the second element of the received page to the new location, according to the modification list. 9. A method for selectively altering the display of page elements, said method comprising: a. sending, by a server to a web browser, a page dynamically generated by a plurality of code fragments executing on the server comprising an executable function and a plurality of elements, a first element of the plurality of elements generated by a first code fragment of the plurality of code fragments and designated by a first identifier;b. receiving, by the server from the web browser, a request to update a portion of the page;c. executing the first code fragment of the plurality of code fragments to produce a second element and a second identifier;d. determining, by the server, a correspondence between the second identifier and first identifier, responsive to the second element and first element both being generated by the first code fragment; ande. sending, by the server to the web browser, the second element and a modification list comprising the first identifier and second identifier,wherein the web browser displays an updated page incorporating the second element by replacing the first element in the page identified by the first identifier with the second element and replacing the first identifier with the second identifier according to the modification list. 10. The method of claim 9, wherein the executable function comprises a Javascript function. 11. The method of claim 9 wherein the plurality of elements comprises a plurality of XML elements. 12. The method of claim 9 wherein step (b) comprises receiving a request comprising the value of at least one user input. 13. The method of claim 9, wherein step (c) comprises executing code to produce a plurality of updated elements and a corresponding plurality of identifiers. 14. The method of claim 13, wherein step (e) comprises sending, to the web browser, a response comprising a plurality of elements and a corresponding plurality of identifiers, each of the plurality of identifiers identifying an element in the page. 15. A system for selectively altering the display of page elements, said system comprising: a client computer: receiving a page dynamically generated by a plurality of code fragments executing on a server, comprising an executable function and a plurality of elements, each element generated by a code fragment of the plurality of code fragments and designated by an identifier,displaying, in a web browser, the received page, andexecuting, in response to at least one user input, the executable function, the executable function sending a request to the server, the request initiating execution of a first code fragment of the plurality of code fragments to generate an updated element; anda transceiver executing on the server to: receive, from the web browser, the request, andsend, to the web browser, the updated element and a modification list comprising an identifier identifying a first element in the page also generated by execution of the first code fragment, the modification list generated by a partial page regenerator responsive to using a map of correspondences to identify page elements and updated elements generated by the same code fragments,wherein the web browser of the client displays an updated page incorporating the updated element by replacing the first element in the page with the updated element according to the modification list. 16. The system of claim 15, wherein the executable function comprises a Javascript function. 17. The system of claim 15 wherein the plurality of elements comprises a plurality of XML elements. 18. The system of claim 15 wherein the transceiver receives a request comprising the value of at least one user input. 19. The system of claim 15, wherein the partial page regenerator produces a plurality of updated elements and a corresponding plurality of identifiers. 20. The system of claim 19, wherein the transceiver sends, to the web browser, a response comprising a plurality of elements and a corresponding plurality of identifiers, each of the plurality of identifiers identifying an element in the page.
