dep0066 outgoingmessage prototype headers outgoingmessage prototype headernames

Type: Runtime

The http module OutgoingMessage.prototype._headers and OutgoingMessage.prototype._headerNames properties are deprecated. Use one of the public methods (e.g. OutgoingMessage.prototype.getHeader(), OutgoingMessage.prototype.getHeaders(), OutgoingMessage.prototype.getHeaderNames(), OutgoingMessage.prototype.hasHeader(), OutgoingMessage.prototype.removeHeader(), OutgoingMessage.prototype.setHeader()) for working with outgoing headers.

The OutgoingMessage.prototype._headers and OutgoingMessage.prototype._headerNames properties were never documented as officially supported properties.
