<p>Systems and methods for robust, efficient, and secure client-server communication are provided. For example, one method of such client-server communication may involve receiving in the server a long polling HTTP request and a client status message, such as a file offer, via HTTP from the client. Such a file offer may indicate, for example, one or more files that are available for transfer from the client. Thereafter, the server may issue a command, such as a file request, as a response to the long polling HTTP request. Such a file request may request at least one of the one or more files that are available for transfer. There-after, the server may receive the at least one of the one or more files from the client via FTP.</p> |
