Device Transfer of a Server Stored Data Item Based on Item ID and Determined Nature of Intended Destination

A non-transitory computer readable medium comprising computer executable instructions for receiving data items, from a file processing system in a communication network on behalf of a first device, at a second device, the second device being coupled to the communication network via the file processing system, the file processing system being interposed between the first device and the second device, the computer executable instructions comprising instructions for:

• the second device enabling the file processing system to determine capabilities of the second device for handling file types for the data items;
• when the second device is not capable of handling a first file type for an original data item intercepted by the file processing system during an original communication sent by an originating device to the first device, the second device receiving from the file processing system a unique ID and an indication of the first file type without the original data item;
• and
• when the second device is capable of handling a second file type for the original data item, the second device receiving from the file processing system on behalf of the first device in completing a subsequent communication either the original data item or a processed data item according to the capabilities of the second device;
• the file processing system having associated the unique ID with the original data item, cached the original data item and the unique ID, sent the unique ID and the original data item to the first device in completing the original communication, received the unique ID from the first device in the subsequent communication, and having determined whether the data item is associated with the first file type or the second file type in determining whether the second device is capable of handling the original data item.

A second device configured for receiving data items, from a file processing system in a communication network on behalf of a first device, the second device being coupled to the communication network via the file processing system, the file processing system being interposed between the first device and the second device, the second device comprising a communications subsystem for communicating data items, a processor, and a memory storing computer executable instructions and data to configure the second device to:

• enable the file processing system to determine capabilities of the second device for handling file types for the data items;
• when the second device is not capable of handling a first file type for an original data item intercepted by the file processing system during an original communication sent by an originating device to the first device, receive from the file processing system a unique ID and an indication of the first file type without the original data item;
• and
• when the second device is capable of handling a second file type for the original data item, receive from the file processing system on behalf of the first device in completing a subsequent communication either the original data item or a processed data item according to the capabilities of the second device;
• the file processing system having associated the unique ID with the original data item, cached the original data item and the unique ID, sent the unique ID and the original data item to the first device in completing the original communication, received the unique ID from the first device in the subsequent communication, and having determined whether the data item is associated with the first file type or the second file type in determining whether the second device is capable of handling the original data item.
