optimizing a selection of archivable objects for one or more archives for a web page; and

generating a number of archives equal to the number of connections to use to deliver one or more archives, the one or more archives comprising the optimized selection of archivable objects;

delivering the one or more archives, wherein each of the one or more archives comprises a plurality of archivable objects referenced within the web page.

9. The computer program product of claim 8, wherein optimizing a selection of archivable objects further comprises selecting archivable objects for inclusion in one or more archives to be generated by the archiver, the content of the archives comprising one or more archivable objects from the web page according to an object prioritization.

10. The computer program product of claim 9, wherein optimizing a selection of archivable objects further comprises scanning a document object model (DOM) tree indicating the structure of the web page to determine the objects referenced within the web page.

11. The computer program product of claim 10, wherein optimizing a selection of archivable objects further comprises assigning a priority to the archivable objects according to one or more prioritization criteria.

12. The computer program product of claim 11, wherein the prioritization criteria comprises a number of descendent objects of the object in the DOM tree.

13. The computer program product of claim 11, wherein the prioritization criteria comprises a hierarchical level of the object in a document object master (DOM) tree.

14. The computer program product of claim 11, wherein selecting archivable objects for inclusion in one or more archives comprises selecting an archivable object for inclusion in response to a determination that a size of the object is less than a threshold size.

15. The computer program product of claim 11, wherein generating a number of archives further comprises sorting the archivable objects in the one or more archives according to priority, such that higher priority archivable objects are closer to a beginning of the archive than lower priority archivable objects.

16. The computer program product of claim 8 wherein generating a number of archives further comprises compressing the one or more archives.

17. A computer program product comprising a computer readable medium having computer usable program code programmed for reducing loading time of a web page, the operations of the computer program product comprising:
