<p>Receipt of virtually all messages (with the exception of some purely service ones as well as the plain-text messages used in the protocol for creating an authorization key) must be acknowledged.
This requires the use of the following service message (not requiring an acknowledgment):</p>
<pre><code>msgs_ack#62d6b459 msg_ids:Vector&lt;long&gt; = MsgsAck;</code></pre>
<p>A server usually acknowledges the receipt of a message from a client (normally, an RPC query) using an RPC response. If a response is a long time coming, a server may first send a receipt acknowledgment, and somewhat later, the RPC response itself.</p>
<p>A client normally acknowledges the receipt of a message from a server (usually, an RPC response) by adding an acknowledgment to the next RPC query if it is not transmitted too late (if it is generated, say, 60-120 seconds following the receipt of a message from the server). However, if for a long period of time there is no reason to send messages to the server or if there is a large number of unacknowledged messages from the server (say, over 16), the client transmits a stand-alone acknowledgment. </p>

<p>In certain cases, a server may notify a client that its incoming message was ignored for whatever reason. Note that such a notification cannot be generated unless a message is correctly decoded by the server.</p>

<p>The intention is that error_code values are grouped (error_code &gt;&gt; 4): for example, the codes 0x40 - 0x4f correspond to errors in container decomposition.</p>
<p>Notifications of an ignored message do not require acknowledgment (i.e., are irrelevant).</p>
<p><strong>Important:</strong> if server_salt has changed on the server or if client time is incorrect, any query will result in a notification in the above format. The client must check that it has, in fact, recently sent a message with the specified msg_id, and if that is the case, update its time correction value (the difference between the client&#39;s and the server&#39;s clocks) and the server salt based on msg_id and the server_salt notification, so as to use these to (re)send future messages. In the meantime, the original message (the one that caused the error message to be returned) must also be re-sent with a better msg_id and/or server_salt.</p>

<p>In addition, the client can update the server_salt value used to send messages to the server, based on the values of RPC responses or containers carrying an RPC response, provided that this RPC response is actually a match for the query sent recently.
