      Description copied from interface: `BHttpConnection`
      Checks if input data is available from the connection. May wait for the specified time until some data becomes available. Note that some implementations may completely ignore the timeout parameter.
      Specified by:
        `isDataAvailable` in interface `BHttpConnection`
      Parameters:
        `timeout` - the maximum time to wait for data
      Returns:
        true if data is available; false if there was no data available even after waiting for `timeout`.

    - #### isStale

          public boolean isStale()
                          throws IOException

      Description copied from interface: `BHttpConnection`
      Checks whether this connection has gone down. Network connections may get closed during some time of inactivity for several reasons. The next time a read is attempted on such a connection it will throw an IOException. This method tries to alleviate this inconvenience by trying to find out if a connection is still usable. Implementations may do that by attempting a read with a very small timeout. Thus this method may block for a small amount of time before returning a result. It is therefore an expensive operation.
      Specified by:
        `isStale` in interface `BHttpConnection`
      Returns:
        `true` if attempts to use this connection are likely to succeed, or `false` if they are likely to fail and this connection should be closed

        `IOException`
