view stream_proxy_protocol.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.
