Abstract

An attachment received from a webclient for a message in composition can be saved by an HTTP server in a storage system. Location information for the attachment can be stored in a database in a record associated with the webclient. If the HTTP server is unexpectedly unavailable, a backup HTTP server can locate the attachment using the record in the database and provide the attachment to a messaging server when the user is ready to send the message.

Claims

1. A method comprising:

receiving, at a first HTTP server from a webclient, an attachment associated with an email;

storing, by the first HTTP server on a storage device, the attachment;

storing, by the first HTTP server on a database, storage device location information for the attachment;

receiving a request for service at a second HTTP server from the webclient;

determining, at the second HTTP server, identification information for the webclient;

retrieving, by the second HTTP server from the database, the storage device location information;

retrieving the attachment by the second HTTP server from the storage device using the storage device location information; and

transmitting the attachment to a mail server.

2. The method of claim 1, wherein determining the identification information for the webclient comprises determining a session identifier from data stored on a device executing the webclient.

3. The method of claim 1, further comprising updating, by the first HTTP server, a state of the webclient in the database.

4. The method of claim 1, further comprising removing, by the second HTTP server, the storage device location information from the database.

5. A system, comprising:

a memory comprising instructions; and

a processor coupled to the memory, wherein the processor, when executing the instructions, effectuates operations comprising;

receiving a request for service from a webclient that has established a communications session with a server that is no longer accessible;

determining identification information for the webclient;

retrieving storage device location information for an attachment;

retrieving the attachment from a storage device using the storage device location information; and

transmitting the attachment to a messaging server.

6. The system of claim 5, wherein the identification information for the webclient comprises a session identifier.

7. The system of claim 5, wherein the storage device location information is retrieved from a database.

8. The system of claim 7, wherein the operations further comprise updating a state of the webclient in the database.

9. The system of claim 5, wherein the storage device location information was stored by the server that is no longer accessible.

10. The system of claim 5, wherein the operations further comprise receiving a request to transmit a message associated with the attachment.

11. A computer-implemented method comprising:

receiving, at a hypertext transfer protocol (HTTP) server, from a webclient, an attachment associated with a message composed on the webclient;

storing, by the HTTP server on a storage device accessible by a second HTTP server, the attachment; and

storing, by the HTTP server, storage device location information for the attachment.

12. The computer-implemented method of claim 11, further comprising associating the storage device location information with a record associated with the webclient in a database.

13. The computer-implemented method of claim 12, further comprising updating a state of the webclient in the database.

14. The computer-implemented method of claim 12, wherein storing the storage device location information for the attachment comprises generating a record in the database comprising a session identifier associated with the webclient.

15. The computer-implemented method of claim 12, wherein the database is accessible by the second HTTP server.

16. The computer-implemented method of claim 11, further comprising receiving an indication that the webclient is in a message composition state.

17. A non-transitory computer-readable storage medium comprising computer-executable instructions, which when executed by a processor, cause a processor to effectuate operations comprising:

receiving a request for service from a webclient that has established a communications session with a server that is no longer accessible;

determining identification information for the webclient;

retrieving storage device location information for an attachment;

retrieving the attachment from a storage device using the storage device location information; and

transmitting the attachment to a messaging server.

18. The non-transitory computer-readable storage medium of claim 17, wherein the identification information for the webclient comprises a session identifier.

19. The non-transitory computer-readable storage medium of claim 17, the storage device location information is retrieved from a database.

20. The non-transitory computer-readable storage medium of claim 19, wherein the operations further comprise updating a state of the webclient in the database.

21. The non-transitory computer-readable storage medium of claim 17, wherein the wherein the storage device location information was stored by the server that is no longer accessible.

22. The non-transitory computer-readable storage medium of claim 18, wherein the operations further comprise receiving a request to transmit a message associated with the attachment.
