IRCv3.3 Client Capability Negotiation |
spec |
true |
|
|
The LS subcommand now has the version 303, in addition to the existing
version 302.
When using version 303, any CAP LS reply sent by the server will be
proceeded by one or more RPL_ISUPPORT (005) numerics containing the current
RPL_ISUPPORT tokens advertised by the server.
There is no modification to the CAP LS reply itself with version 303 – the
only difference with this version is that the RPL_ISUPPORT numerics are now
sent at the start of the response.
This specification uses the RPL_ISUPPORT numeric:
| No. | Label | Format |
|---|---|---|
| 005 | RPL_ISUPPORT |
<client> <1-13 tokens> :are supported by this server |
