109an error that your URL scheme is not supported even though your URL is a

113The pseudo-header C<Redirect> only exists when the request was a result
114of an internal redirect. In that case it is an array reference with
115the C<($data, $headers)> from the redirect response. Note that this
116response could in turn be the result of a redirect itself, and C<<
117$headers->{Redirect}[1]{Redirect} >> will then contain the original

218In even rarer cases you want total control over how AnyEvent::HTTP
219establishes connections. Normally it uses L<AnyEvent::Socket::tcp_connect>
220to do this, but you can provide your own C<tcp_connect> function -
221obviously, it has to follow the same calling conventions.
222
223There are probably lots of weird uses for this function, starting from
224tracing the hosts C<http_request> actually tries to connect, to (inexact

790
791AnyEvent::HTTP uses the AnyEvent::Socket::tcp_connect function for
792the actual connection, which in turn uses AnyEvent::DNS to resolve
793hostnames. The latter is a simple stub resolver and does no caching
794on its own. If you want DNS caching, you currently have to provide
795your own default resolver (by storing a suitable resolver object in
796C<$AnyEvent::DNS::RESOLVER>).
