annotate src/http/modules/ngx_http_memcached_module.c @ 5008:fd84344f1df7
Fixed and improved the "*_bind" directives of proxying modules.
The "proxy_bind", "fastcgi_bind", "uwsgi_bind", "scgi_bind" and
"memcached_bind" directives are now inherited; inherited value
can be reset by the "off" parameter. Duplicate directives are
now detected. Parameter value can now contain variables.
