header()

header is used to send a raw HTTP header. See the HTTP/1.1 specification for more information on HTTP headers.

Inputs: header: The header string. There are two special-case header calls. The first is a header that starts with the string “HTTP/” (case is not significant), which will be used to figure out the HTTP status code to send. response_code: Forces the HTTP response code to the specified value. Note that this parameter only has an effect if the header is not empty.

Returns: No value is returned.
