When the service is running with trace log level it wraps the
http.ResponseWriter
to log extra information. The problem is that the new type does not keep all the functions from the embedded type. Instead we have to implement them ourselves, however only Write() was implemented. ThusHijack()
could not be called on the writer. To prevent these issues we would implement all the interfaces that the inner type supports (Header, WriteHeader, Flush, Hijack).Fixes #17749
