====== S2C Packet 11: Server Info ======

**//THIS IS A DRAFT AND SHOULD NOT YET BE IMPLEMENTED//**

Informs the client about the name, version and capabilities of the server.
This is sent in response to [[sockchat:c2s:client-info|C2S Packet 3: Client Info]] if sent to the client and must be ignored if received after [[sockchat:c2s:authz-attempt|C2S Packet 1: Authorization Attempt]] has already been handled.

The capabilities that are sent back to the client must not contain any that do not appear in the list sent by the client. If the client is not satisfied with the capabilities it received, it may close the connection.

The format of the server identification string is entirely up to the developer of the server and is not used for capability checking, similar to the [[https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Server|HTTP Server header]].

===== Format =====

^ Index ^ Type ^ Description ^
|  0 |  ''%%11%%''  | Server Info packet ID |
|  1 |  [[sockchat:types#string|string]]  | Server identification |
|  2 |  [[sockchat:types#collection|collection]]  | Capabilities supported by the server |

===== Examples =====

The examples for [[sockchat:c2s:client-info#examples|C2S Packet 3: Client Info]] apply here as well, since this packet is a direct response to it and will never occur without it being issued.
