6. A method according to claim 1, further comprising:

prior to sending, determining if any of the plurality of objects is appropriate for division into predetermined portions; and

dividing each appropriate one of the plurality of objects into predetermined portions prior to sending.

7. A method according to claim 6, further comprising compressing at least one of the plurality of objects that is not appropriate for division prior to sending

8. A method according to claim 1, further comprising:

holding the subsequent predetermined portions pending receipt of a request for the subsequent predetermined portions.

9. A method according to claim 1, wherein the at least one of the plurality of objects comprises two or more of the plurality of objects.

10. A method according to claim 1, wherein the network is a wireless network and the server is a web server.

11. A method according to claim 1, wherein the sending a first predetermined portion is handled using a Hyper-Text Transfer Protocol connection and the sending subsequent predetermined portions is handled using another predetermined protocol connection after the Hyper-Text Transfer Protocol connection has closed.

12. A method for receiving multimedia content in a client-server system in a network, wherein the multimedia content comprises a plurality of objects, the method comprising:

receiving a predetermined portion of each of the plurality of objects through the network at the client, wherein the predetermined portion is less than a complete object for at least one of the plurality of objects; and

after receiving the first predetermined portion of each of the plurality of objects, successively receiving subsequent predetermined portions of each of the plurality of objects until all portions of the plurality of objects have been received.

13. A method according to claim 12, further comprising:

before receiving, sending a request for multimedia content, where the request comprises information related to the sending of objects.

14. A method according to claim 13, wherein the information related to the sending of objects comprises information related to objects for which sending is to be delayed.

15. A method according to claim 13, wherein the information related to the sending of objects comprises information related to the ordering in which objects are to be sent.

16. A method according to claim 12, wherein the receiving of subsequent predetermined portions occurs only after sending a request for subsequent predetermined portions.

17. A method according to claim 12, wherein the at least one of the plurality of objects comprises two or more of the plurality of objects.

18. A method according to claim 12, wherein the network is a wireless network and the client is a mobile device.

19. A method according to claim 12, wherein the receiving a first predetermined portion is handled using a Hyper-Text Transfer Protocol connection and the receiving subsequent predetermined portions is handled using another predetermined protocol connection after the Hyper-Text Transfer Protocol connection has closed.

20. A method according to claim 12, further comprising:

prior to receiving, determining if the multimedia content is available in a cache; and

where first predetermined portions of each of the at least one of the plurality of objects are available in the cache but subsequent predetermined portions of each of the at least one of the plurality of objects are not available in the cache, sending a request for the subsequent predetermined portions without receiving the first predetermined portions.
