view stream_udp_upstream_hash.t @ 1434:fc8341cf92a3
Tests: removed ngx_parse_inet6_url() "::" test from proxy.t.
It results in WSAEADDRNOTAVAIL on win32, be the connection errors detected,
which leads to connect() alert. On other systems, connect() is successful
but it uses the default port (80), which is out of documented ports range.
