Abstract

The present invention is directed to a mechanism that permits a browser to assemble content dynamically from cached static elements and dynamic elements retrieved from a data network.

Claims

1. A method of operating a browser application with a connection to a data network comprising:

(a) retrieving a template containing one or more inclusion markups;

(b) parsing the template for the inclusion markups;

(c) retrieving from a server connected to the data network an included data object identified in an inclusion markup;

(c) assembling the template and the included data objects to create a data page that can be displayed to the user.

2. The invention of claim 1 wherein the template is retrieved from a cache.

3. The invention of claim 1 wherein the inclusion markup identifying the included data object also identifies at least one alternative source for the included data object.

4. The invention of claim 1 wherein the template and the data objects are expressed in XML.

5. The invention of claim 1 wherein the template is used to create a document object model tree.

6. The invention of claim 5 wherein the document object model tree is modified in accordance with the inclusion markups.

7. The invention of claim 1 wherein the inclusion markups are expressed using ESI.

8. A device-readable medium storing a scripting program for performing a method of operating a browser application with a connection to a data network, the method comprising the steps of:

(a) retrieving a template containing one or more inclusion markups;

(b) parsing the template for the inclusion markups;

(c) retrieving from a server connected to the data network an included data object identified in an inclusion markup;

(c) assembling the template and the included data objects to create a data page that can be displayed to the user.

9. The invention of claim 8 wherein the template is retrieved from a cache.

10. The invention of claim 8 wherein the inclusion markup identifying the included data object also identifies at least one alternative source for the included data object.

11. The invention of claim 8 wherein the template and the data objects are expressed in XML.

12. The invention of claim 8 wherein the template is used to create a document object model tree.

13. The invention of claim 12 wherein the document object model tree is modified in accordance with the inclusion markups.

14. The invention of claim 8 wherein the inclusion markups are expressed using ESI.
