Sends the response line and headers.
|
||
|
|
This function sends the response line with the `status_code`, and
|
||
|
|
automatically
|
||
|
|
sends one header: either "Content-Length" or "Transfer-Encoding".
|
||
|
|
If `content_length` is negative, then "Transfer-Encoding: chunked" header
|
||
|
|
is sent, otherwise, "Content-Length" header is sent.
|
||
|
|
|
||
|
|
NOTE: If `Transfer-Encoding` is `chunked`, then message body must be sent
|
||
|
|
using `mg_send_http_chunk()` or `mg_printf_http_chunk()` functions.
|
||
|
|
Otherwise, `mg_send()` or `mg_printf()` must be used.
|
||
|
|
Extra headers could be set through `extra_headers`. Note `extra_headers`
|
||
|
|
must NOT be terminated by a new line.
