# header
|
|
|
|
## Name
|
|
|
|
*header* - modifies the header for responses.
|
|
|
|
## Description
|
|
|
|
*header* ensures that the flags are in the desired state for responses. The modifications are made transparently for
|
|
the client.
|
|
|
|
## Syntax
|
|
|
|
~~~
|
|
header {
|
|
ACTION FLAGS...
|
|
ACTION FLAGS...
|
|
}
|
|
~~~
|
|
|
|
* **ACTION** defines the state for DNS message header flags. Actions are evaluated in the order they are defined so last one has the
|
|
most precedence. Allowed values are:
|
|
* `set`
|
|
* `clear`
|
|
* **FLAGS** are the DNS header flags that will be modified. Current supported flags include:
|
|
* `aa` - Authoritative(Answer)
|
|
* `ra` - RecursionAvailable
|
|
* `rd` - RecursionDesired
|
|
|
|
## Examples
|
|
|
|
Make sure recursive available `ra` flag is set in all the responses:
|
|
|
|
~~~ corefile
|
|
. {
|
|
header {
|
|
set ra
|
|
}
|
|
}
|
|
~~~
|
|
|
|
Make sure "recursion available" `ra` and "authoritative answer" `aa` flags are set and "recursion desired" is cleared in all responses:
|
|
|
|
~~~ corefile
|
|
. {
|
|
header {
|
|
set ra aa
|
|
clear rd
|
|
}
|
|
}
|
|
