Currently if we extract the
DialInfo
from aRequest
Context
in a customTransport
during an active health check, then theUpstream
in theDialInfo
will be nil.This PR attempts to set the
Upstream
to a sensible value, based on wether or not theUpstream
has been overridden in the active health check's config.This is useful when using a custom Transport for the
reverse_proxy
module, as it makesGetDialInfo
behave similarly in active health check requests and client requests.
