+ * The return is a json encoded with:
+ * - 'transferid'
+ * - 'needed' chunks
+ * - 'last' checked chunk
+ * The URL is made of 3 parts, the service url (remote.php/filesync/), the sync
+ * type and the path in ownCloud.
+ * At the moment the only supported sync type is 'oc_chunked'.
+ * The final URL will look like http://.../remote.php/filesync/oc_chunked/path/to/file
