Subject Re: IVY with preemptive authentication
Date Tue, 05 Jun 2018 12:03:30 GMT
Hi Jaikiran,

good to hear that there are at least thoughts on this topic. In my 
opinion it's not as easy as I described it since there are resolvers 
that do not use HTTP as a transport layer. So it feels a bit difficult 
to find the correct place to configure this. But I will be looking 
forward to hear from you.
