- * This class models a connection that retrieves the information pointed

- * on the network, but could be a simple disk read.
- * <p>
- * A URLConnection object is normally created by calling the openConnection()
- * method of a URL object.  This method is somewhat misnamed because it does
- * not actually open the connection.  Instead, it return an unconnected
- * instance of this object.  The caller then has the opportunity to set
- * various connection options prior to calling the actual connect() method.
- * <p>
- * After the connection has been opened, there are a number of methods in
- * this class that access various attributes of the data, typically
- * represented by headers sent in advance of the actual data itself.
- * <p>
- * Also of note are the getInputStream and getContent() methods which allow
- * the caller to retrieve the actual data from the connection.  Note that
- * for some types of connections, writing is also allowed.  The setDoOutput()
- * method must be called prior to connecing in order to enable this, then
- * the getOutputStream method called after the connection in order to
- * obtain a stream to write the output to.
- * <p>
- * The getContent() method is of particular note.  This method returns an
- * Object that encapsulates the data returned.  There is no way do determine
- * the type of object that will be returned in advance.  This is determined
- * by the actual content handlers as described in the description of that
- * method.
