view src/http/ngx_http_copy_filter_module.c @ 9036:6cf8ed15fd00 quic
Set default listen socket type in http.
The type field was added in 7999d3fbb765 at early stages of QUIC implementation
and was not initialized for default listen. Missing initialization resulted in
default listen socket creation error.
