SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_handler_set_host(nng_http_handler *handler, const char *host);DESCRIPTION
The nng_http_handler_set_host() function is used to limit the scope of the
handler so that it will only be called when the specified host matches
the value of the Host: HTTP header.
| This can be used to create servers with multiple handlers for virtual hosting. |
The value of the host can include a colon and port, and should match
exactly the value of the Host header sent by the client. (Canonicaliztion
of the host name is performed though.)
| As the server framework does not support listening on multiple ports, the port number can be elided. The matching test only considers the hostname or IP address, and ignores any trailing port number. |
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_ENOMEM-
Insufficient free memory to perform the operation.
NNG_ENOTSUP-
No support for HTTP in the library.
