Funambol compression mechanism is based on the exchange of standard HTTP headers (Accept-Encoding, Content-Encoding, Uncompressed-Content-Length), as it is recently specified by OMA. For more information you can refer to the Funambol DS Server Architecture Design Document, par. 1.2.1.
It's been reported that, on some network, the compressed stream is corrupted when received by the client. That has been verified with some operator using a WAP gateway, while it works with a web connection.
Since version 6.5 of the Funambol clients, in case of error during the decompression of the data, the sync is automatically retried with compression disabled. This is transparent to the user, apart the loss of performance.
