#dump(header = '', dev = '') ⇒ Object

Message header must be given as the first argument for performance reason. (header is dumped to dev, too) If no dev (the second argument) given, this method returns a dumped String.

#dump_chunked(header = '', dev = '') ⇒ Object

Dumps message body with chunked encoding to given dev. dev needs to respond to <<.

Message header must be given as the first argument for performance reason. (header is dumped to dev, too) If no dev (the second argument) given, this method returns a dumped String.
