annotate src/core/ngx_connection.h @ 5104:93713d4b99c3
Removed c->single_connection flag.
The c->single_connection was intended to be used as lock mechanism
to serialize modifications of request object from several threads
working with client and upstream connections. The flag is redundant
since threads in nginx have never been used that way.
