#include <nng/nng.h> #include <nng/supplemental/http/http.h> int nng_http_res_set_header(nng_http_res *res, const char *key);
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
equivalent, whereas the value
Host: is not a legal header key.
This function returns 0 on success, and non-zero otherwise.
No header with the key key was present.
No support for HTTP in the library.
