Method and apparatus for resource downloading over a network from multiple sources

1. A method for file downloading, the method comprising:

transmitting a first request to a server to start a downloading process of a file;

receiving a first destination address and a first cookie for the downloading process,

wherein the first destination address and the first cookie are associated with the file;

storing the first destination address, the first cookie, a link address associated with the file, and a web address associated with the link address;

detecting an interruption of the downloading process;

responsive to detection of an interruption of the downloading process, transmitting a second request to the server for a second destination address and a second cookie based on the link address and web address, wherein the second destination address and the second cookie are associated with the file; and

resuming the downloading process of the file using the second destination address and the second cookie.

2. The method of claim 1 , wherein the detection of an interruption of the downloading process further comprises detecting that at least one of the first destination address and the first cookie is invalid.

3. The method of claim 1 , wherein the detection of an interruption of the downloading process further comprises detecting that at least one of the first destination address and the first cookie has expired.

4. The method of claim 1 , wherein the second request is generated based on the link address, and wherein a header of the second request includes the web address.

5. The method of claim 1 , wherein the resumption of the downloading process of the file using the second destination address and the second cookie comprises resuming the downloading process based on a progress of the downloading process before the interruption occurs.

6. The method of claim 1 , wherein the resumption of the downloading process of the file using the second destination address and the second cookie comprises transmitting a third request to download the file, wherein the third request includes an attribute that represents a size of the file that has not been downloaded when the interruption of the downloading process occurs.

7. The method of claim 6 , wherein the third request is an HTTP (HyperText Transfer Protocol) request, and wherein the attribute is included in the range unit of the third request.

8. An apparatus for file downloading comprising:

a memory device that stores instructions and

at least one hardware processor configured to execute the instructions to:

transmit a first request to a server to start a downloading process of a file;

receive a first destination address and a first cookie for the downloading process, wherein the first destination address and the first cookie are associated with the file;

store the first destination address, the first cookie, a link address associated with the file, and a web address associated with the link address;

detect an interruption of the downloading process;

responsive to detection of an interruption of the downloading process, transmit a second request to the server for a second destination address and a second cookie based on the link address and web address, wherein the second destination address and the second cookie are associated with the file; and

resume the downloading process of the file using the second destination address and the second cookie.

9. The apparatus of claim 8 , wherein the detection of an interruption of the downloading process further comprises the at least one hardware processor being configured to execute the instructions to detect that at least one of the first destination address and the first cookie is invalid.

10. The apparatus of claim 8 , wherein the detection of an interruption of the downloading process further comprises the at least one hardware processor being configured to execute the instructions to detect that at least one of the first destination address and the first cookie has expired.

11. The apparatus of claim 8 , wherein the second request is generated based on the link address, and wherein a header of the second request includes the web address.

12. The apparatus of claim 8 , wherein the resumption of the downloading process of the file using the second destination address and/or the second cookie comprises resuming the downloading process based on a progress of the downloading process before the interruption occurs.

13. The apparatus of claim 8 , wherein the resumption of the downloading process of the file using the second destination address and the second cookie comprises the at least one hardware processor being configured to execute the instructions to transmit a third request to download the file, wherein the third request includes an attribute that represents a size of the file that has not been downloaded when the interruption of the downloading process occurs.

14. The apparatus of claim 8 , wherein the third request is an HTTP (HyperText Transfer Protocol) request, and wherein the attribute is included in the range unit of the third request.

15. A non-transitory readable medium that stores a program that, when executed by a processor, causes the processor to perform a method for file downloading, the method comprising:

transmitting a first request to a server to start a downloading process of a file;

receiving a first destination address and a first cookie for the downloading process, wherein the first destination address and the first cookie are associated with the file;

storing the first destination address, the first cookie, a link address associated with the file, and a web address associated with the link address;

detecting an interruption of the downloading process;

responsive to detection of an interruption of the downloading process, transmitting a second request to the server for a second destination address and a second cookie based on the link address and web address, wherein the second destination address and the second cookie are associated with the file; and

resuming the downloading process of the file using the second destination address and the second cookie.

16. The medium of claim 15 , wherein the detection of an interruption of the downloading process further comprises detecting that at least one of the first destination address and the first cookie is invalid.

17. The medium of claim 15 , wherein the detection of an interruption of the downloading process further comprises detecting that at least one of the first destination address and the first cookie has expired.

18. The medium of claim 15 , wherein the second request is generated based on the link address, and wherein a header of the second request includes the web address.

19. The medium of claim 15 , wherein the resumption of the downloading process of the file using the second destination address and the second cookie comprises resuming the downloading process based on a progress of the downloading process before the interruption occurs.

20. The medium of claim 15 , wherein the resumption of the downloading process of the file using the second destination address and the second cookie comprises transmitting a third request to download the file, wherein the third request includes an attribute that represents a size of the file that has not been downloaded when the interruption of the downloading process occurs.
