Abstract

A Content Request System (CRS) is operated to request the downloading of content from a Content Server to a Content Viewing System using a proxy and an Intermediary Server. CRS obtains parameters related to the download including at least an identification of data to be downloaded, the identity of a CS containing the identified data, and the identity of an IS to which the identified data is to be downloaded. CRS creates a proxy that facilitates the downloading of the identified data from the identified CS, the proxy containing the obtained parameters. The proxy is transmitted to the identified IS which uses the proxy to download the identified data from the identified CS in accordance with the parameters contained in the proxy. The identified IS then transfers the downloaded data to CVS.

13. A method for facilitating the transferring of data from at least one server to a client device, the method comprising:

receiving a proxy containing parameters including at least an identification of the data to be downloaded and the identity of the at least one server;

using the proxy to download the identified data from the identified at least one server; and

transferring the downloaded data to the client device.

14. The method of claim 13, further comprising:

storing the received proxy;

wherein receiving proxy comprises receiving a proxy containing parameters including a time at which the identified data is to be downloaded from the identified at least one server; and

wherein using the proxy comprises using the stored proxy to download the identified data from the identified at least one server at the time indicated in the parameters of the proxy.

15. The method of claim 13, wherein receiving a proxy comprises receiving a proxy containing parameters including user information necessary to access the identified data on the identified at least one server;

and

wherein using the proxy comprises using the user information contained in the proxy to download the identified data from the identified at least one server.

16. The method of claim 13, further comprising:

storing the downloaded data; and

wherein transferring the downloaded data comprises;

sending an electronic message to a user containing a link to the stored data; and

transmitting the stored data to a client device being operated by the user upon the link being accessed.

17. A system for facilitating the transfer of data from at least one server to a client device, the system comprising:

programming in a user device, which causes the user device, in response to user input, to provide parameters to a computer, the parameters including at least the identity of the data to be downloaded and the identity of the at least one server; and

the computer, in response to receiving the parameters from the user device, using the parameters to cause the identified data to be downloaded from the at least one server to the computer, and in response to a communication received from the client device, transferring the downloaded data to the client device.

18. The system of claim 17, further comprising a user device containing the programming.

19. A system for facilitating the transferring of data from at least one server to a client device, the system comprising:
