* For caddy v1 in our org This RP changes all imports for caddyserver/caddy to coredns/caddy. This is the v1 code of caddy. For the coredns/caddy repo the following changes have been made: * anything not needed by us is deleted * all `telemetry` stuff is deleted * all its import paths are also changed to point to coredns/caddy * the v1 branch has been moved to the master branch * a v1.1.0 tag has been added to signal the latest release Signed-off-by: Miek Gieben <miek@miek.nl> * Fix imports Signed-off-by: Miek Gieben <miek@miek.nl> * Group coredns/caddy with out plugins Signed-off-by: Miek Gieben <miek@miek.nl> * remove this file Signed-off-by: Miek Gieben <miek@miek.nl> * Relax import ordering github.com/coredns is now also a coredns dep, this makes github.com/coredns/caddy fit more natural in the list. Signed-off-by: Miek Gieben <miek@miek.nl> * Fix final import Signed-off-by: Miek Gieben <miek@miek.nl> |

nsid
Name
nsid - adds an identifier of this server to each reply.
Description
This plugin implements RFC 5001 and adds an EDNS0 OPT resource record to replies that uniquely identify the server. This is useful in anycast setups to see which server was responsible for generating the reply and for debugging.
This plugin can only be used once per Server Block.
Syntax
nsid [DATA]
DATA is the string to use in the nsid record.
If DATA is not given, the host's name is used.
Examples
Enable nsid:
example.org {
whoami
nsid Use The Force
}
And now a client with NSID support will see an OPT record with the NSID option:
% dig +nsid @localhost a whoami.example.org
