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

     AnyEvent::HTTP::set_proxy "proxy-url"
         Sets the default proxy server to use. The proxy-url must begin with
-        a string of the form "http://host:port" (optionally "https:...").
+        a string of the form "http://host:port" (optionally "https:..."),
+        croaks otherwise.
+
+        To clear an already-set proxy, use "undef".
 
     $AnyEvent::HTTP::MAX_RECURSE
         The default value for the "recurse" request parameter (default: 10).
