Connection.java (gotHeaders): Removed.

2000-08-10  Bryce McKinlay  <bryce@albatross.co.nz>
	    John Stracke <francis@ecal.com>

	* gnu/gcj/protocol/http/Connection.java (gotHeaders): Removed.
	(connect): Don't falsely claim HTTP/1.1 compliance. Call
	getHttpHeaders().
	(disconnect): Don't unset connected flag.
	(getHeaderField (String)): Call connect() if not connected.
	(getHeaderField (int)): Ditto.
	(getHeaderFieldKey): Ditto.
	(getHttpHeaders): Don't call connect().
	* java/net/HttpURLConnection.java (instanceFollowRedirects,
	gotResponseVals): New fields.
	(getResponseCode): Call getResponseVals() conditionally.
	(getResponseMessage): Ditto.
	(getResponseVals): Call connect(). Don't throw
	FileNotFoundException.
