Abstract
The disclosure is directed to error correction in transmission of data whose state is to be synchronized between a server and a client. When data, e.g., a web page, changes at the server, the changes are sent to the client as a sequence of diffs, where each diff represents an incremental change in the state of the data over a previous diff in the sequence. This can eliminate the need to transmit the whole webpage whenever the web page changes. If a diff is lost in transmission, the state of the webpage at the client becomes invalid. To overcome this problem, the server sends a hash of the webpage state at the server to the client, e.g., at specified intervals. The client or server can compute a hash of the webpage state and compare both the hashes. If they don't match, the client receives the whole webpage.
