void	connect(HttpURLConnection hconn) Opens communication to an HTTP resource.

Method Detail

connect

void connect(HttpURLConnection hconn)
      throws IOException

Opens communication to an HTTP resource. The implementation will presumably at least call URLConnection.connect(), but it may optionally perform other actions as well, such as configuring the request headers as required and writing to the connection's output stream, before returning.

If this object is being used with AuthManager, it will typically be a good idea to call setInstanceFollowRedirects(false), since redirection can be handled by AuthManager.

Parameters:

hconn - URL connection; on entry connect() has not yet been called, but on exit it has

Throws:

IOException
