SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_res_set_header(nng_http_res *res, const char *key);DESCRIPTION
The nng_http_res_del_header() removes all HTTP headers with the
associated key from the response structure res.
The value of key is case insensitive, and should not include the final
colon in an HTTP header. For example, specifying Host or hOSt are
equivalent, whereas the value Host: is not a legal header key.
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_ENOENT-
No header with the key key was present.
NNG_ENOTSUP-
No support for HTTP in the library.
