Whatever call a javascript uses today to do a GET/POST etc with a URI as an argument could issue more DNS queries than just query for A/AAAA etc. I am not talking about doing an end run around the local policy for DNS queries where the script is running. I am just after adding SRV/URI etc to the DNS queries that are made where today A and AAAA is made. Regardless of where that is. You are unless you intend to build in a CORS mechanism in the DNS protocol that can talk about web origins. Otherwise the server doesn't know well enough to be able to decide. I'm assuming that this is too much work.
