<p>From the standpoint of the high-level component, the client and the server exchange <em>messages</em> inside a <em>session</em>. The session is attached to the client device (the application, to be more exact) rather than a specific WebSocket/http/https/tcp connection. In addition, each session is attached to a <em>user key ID</em> by which authorization is actually accomplished.</p>
|
||||
<p>Several connections to a server may be open; messages may be sent in either direction through any of the connections (a response to a query is not necessarily returned through the same connection that carried the original query, although most often, that is the case; however, in no case can a message be returned through a connection belonging to a different session). When the UDP protocol is used, a response might be returned by a different IP address than the one to which the query had been sent.</p>
