| Format: http_request_header ( [ header-name ] ) |
Purpose: Get client request headers. The header-name parameter must be a string that is allowed in request headers from clients. For a detailed description of request headers see RFC-2068 which defines the HTTP/1.1 protocol.
Return Values: If header-name is given, the function returns a string denoting the request header value for the header name if header-name occurs in the request header. If header-name doesn't occur in the request header, null is returned. If header-name is not given, an object is returned denoting the whole request header. Each object field name/value corresponds to a header name/value in the request header.
