annotate src/http/ngx_http_special_response.c @ 6432:cf3e75cfa951
Added variables support to server_tokens.
It can now be set to "off" conditionally, e.g. using the map
directive.
An empty value will disable the emission of the Server: header
and the signature in error messages generated by nginx.
Any other value is treated as "on", meaning that full nginx
version is emitted in the Server: header and error messages
generated by nginx.
