Actually, since there is no "DNS error" code in http1 proxy communication,
if proxy operators do not want to be buried under user complains each time
a popular site has dns problems, they have to force dns resolution in the
browser before relaying any request to the proxy (which will then perform
a second resolution)

That's the only way to get browsers display a dns error page and not a
evil proxy error page when dns is down

So complaining of srv now, but ignoring proxy connexion error handling, is
kind of sad.
