copied!<p>From the protocol specification: <a href="https://github.com/udp/lacewing/blob/0.2.x/relay/current_spec.txt" rel="nofollow">https://github.com/udp/lacewing/blob/0.2.x/relay/current_spec.txt</a></p> <blockquote> <p>As soon as the TCP connection is established, the client should send a single byte of 0 to identify themselves as a non-HTTP client. After this, they may start exchanging messages, of which the Connect request should be the first.</p> </blockquote> <p>On initial connection, non-HTTP clients send byte 0. This is not part of the message - the first actual protocol message comes after this.</p> <blockquote> <pre><code>0 0 11 //lenght 0 .. </code></pre> </blockquote> <p>The first 0 is that "I'm not an HTTP client" identifier. The rest is the actual message: 0 is the type, which is made up of the variant and the request type type. The 11 is the length of the message, and the 0 is the actual "can I connect".</p> <blockquote> <pre><code>0 4 // lenght 1 // should be the type according to spec (1 for name setting request) .. </code></pre> </blockquote> <p>Again, 0 is the type, made up of the variant and request type. 4 is the length, again, and 1 is the request to Set Name.</p> <p>The initial 0 on connection is a confusing aspect of the protocol because it is mentioned in an odd place, but it is mentioned, nonetheless.</p> <p>Relevant thread in Development forum: <a href="http://community.clickteam.com/threads/79449-Lacewing-message-headers" rel="nofollow">http://community.clickteam.com/threads/79449-Lacewing-message-headers</a></p>
