 The data extracted from the HTTPS RR is stored in the in-memory DNS cache to
 be reused on subsequent uses of the same hostnames.
 
+## limitations

+We have decided to work on the HTTPS RR support by following what seems to be

+and complexities and we might as well avoid them if no one seems to want them.
