Abstract

A method for retrieving a resource such as a data file includes determining an email address of a user requesting the retrieval, and checking whether a characteristic condition associated with said resource is satisfied. If the characteristic condition is not satisfied, for example if the size of the resource exceeds a threshold, a message is returned to the user indicating that said request for retrieval of said resource has been received, and the request is placed in a queue. The queue is processed on the basis of a rule, and the resource retrieved when said queue has been sufficiently processed, when the user can be notified by means of the email address that the resource has been retrieved. Also disclosed is a similar process for uploading data files in response to a request.

Claims

1. A method for retrieving a resource, the method comprising the steps of:

receiving from a user a request for retrieval of a resource;

determining an email address of the user; and

checking whether a characteristic condition associated with said resource is satisfied;

the method further comprising the step, if said characteristic condition is satisfied, of retrieving said resource; and

the method further comprising the steps, if said characteristic condition is not satisfied, of;

returning a message indicating that said request for retrieval of said resource has been received;

determining whether a request for retrieval of said resource is already in a queue for retrieval;

if a request for retrieval of said resource is not already in a queue for retrieval, placing a request in said queue together with said email address; and

if a request for retrieval of said resource is already in said queue for retrieval, associating said email address with the request for retrieval of said resource already in said queue for retrieval;

and the method further comprising the steps of;

processing said queue on the basis of a rule;

retrieving said resource when said queue has been sufficiently processed; and

notifying the user by means of the email address that the resource has been retrieved.

2. The method according to claim 1, wherein the resource comprises a data file.

3. The method according to claim 2, wherein the step of checking whether a characteristic condition associated with said data file is satisfied comprises checking whether said data file is below a predetermined size.

4. A method as claimed in claim 3, wherein checking whether the file is below a determined size comprises determining a likely size of the file based on a file extension of the file.

5. The method according to claim 1, further comprising the step of saving said retrieved resource locally.

6. The method according to claim 5, further comprising, before checking whether a characteristic condition associated with said resource is satisfied, checking whether said resource is stored locally, and, if it is determined that the resource is stored locally, returning a local copy of the resource.

7. The method according to claim 1, comprising determining the email address of the user by sending to the user, in response to receiving said request for retrieval of a resource, a request for the email address of said user.

8. The method according to claim 1, wherein said queue is processed on the basis of a rule relating to the user from which said request was received, the length of time to retrieve said resource, or the bandwidth used to retrieve said resource.

9. The method according to claim 1, wherein only one resource in said queue is retrieved at one time.

10. The method according to claim 1, wherein resources in said queue are only retrieved at certain times.

11. The method according to claim 1, wherein the step of notifying the user comprises sending to said user a message indicating a local address for retrieval of said data file.

17. A computer program product, comprising computer-readable instructions for causing a proxy server to perform the method according to claim 1.

18. A proxy server, suitable for use in a computer system, further comprising a plurality of user computers, the proxy server being configured to perform the method as defined in any of claim 1.

12. A method for uploading a data file, the method comprising the steps of:

receiving from a user a request for a data file to be uploaded;

determining an email address of the user; and

checking whether a characteristic condition associated with said data file is satisfied;

the method further comprising the step, if said characteristic condition is satisfied, of uploading said data file; and

the method further comprising the steps, if said characteristic condition is not satisfied, of;

returning a message indicating that said request for uploading of said data file has been received;

placing said request in a queue together with said email address;

processing said queue on the basis of a rule;

uploading said data file when said queue has been sufficiently processed; and

notifying the user by means of the email address that the data file has been uploaded.

13. The method according to claim 12, wherein the step of checking whether a characteristic condition associated with said data file is satisfied comprises checking whether said data file is below a predetermined size.

14. The method according to claim 12, comprising determining the email address of the user by sending to the user, in response to receiving said request for uploading of the data file, a request for the email address of said user.

15. The method according to any of claim 12, wherein said queue is processed on the basis of a rule relating to the user from which said request was received, the length of time to upload said data file, or the bandwidth used to upload said data file.

16. The method according to any of claim 12, wherein data files in said queue are only uploaded at certain times.
