1690220 - Don't use http rr when proxy CONNECT is in use

Status: RESOLVED FIXED

(Core :: Networking, task, P2)

Description

[Kershaw Chang [:kershaw]]

As described in spec below, we should not query https rr when CONNECT is used.

   Clients using a domain-oriented transport proxy like HTTP CONNECT
   ([RFC7231] Section 4.3.6) or SOCKS5 ([RFC1928]) SHOULD disable SVCB
   support if performing SVCB queries would violate the client's privacy
   intent.

   If the client can safely perform SVCB queries (e.g. via the proxy or
   an affiliated resolver), the client SHOULD follow the standard SVCB
   resolution process, selecting the highest priority option that is
   compatible with the client and the proxy.  The client SHOULD provide
   the final SvcDomainName and port to the proxy, which will perform any
   required A and AAAA lookups.
