+Subject: [PATCH] Merge r1886141, r1886151 from trunk:
+
+* We need to check for (!scheme && (u = strchr(url, ':')) && (u - url) > 14)
+  later as (!scheme || u[0] != '/' || u[1] != '/' || u[2] == '\0') is true
+  for requests with the CONNECT method which we need to decline. But in many
+  cases requests with the CONNECT method have (u - url) > 14 as in this
+  case (u - url) is the length of the FQDN the forward proxy should connect
+  to.
+
+
+mod_proxy_http: follow up to r1886141, axe overlong scheme check.
+
+Since mod_proxy can see CONNECT URIs, "hostname:port" versus "scheme:"
+is hardly distinguishable (we don't want to limit the length of hostnames),
+and we don't allocate the scheme anymore while parsing, let's simply decline
+unrecognized schemes (overlong or not) and be caught by the no-handler case
+if there really is no proxy handler interested.
