Is TLS resumption possible for DNS over TLS
-
Hi,
I have been using DNS over TLS for few days and it seems that establishing a TLS session each time for a single DNS query really takes time.Are there any chance to enable TLS resumption to reduce the overhead of some messages in TLS handshake? It can significantly decrease the query time.

Not yet possible in Unbound. There is an open feature request for that in Unbound itself.
