```
    Update the current connection wide window size to a new size.
    Increasing this value, gives better performance when several data streams are multiplexed
    This is not implemented for HTTP/1.x.
    
    Parameters:
    
    windowSize - the new window size
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - goAway
```
default HttpConnection goAway(long errorCode)
```
    Like goAway(long, int) with a last stream id -1 which means to disallow any new stream creation.
  - goAway
```
default HttpConnection goAway(long errorCode,

```
    Send a go away frame to the remote endpoint of the connection.
    - a GOAWAY frame is sent to the to the remote endpoint with the errorCode and debugData
    - any stream created after the stream identified by lastStreamId will be closed
    - for an errorCode is different than 0 when all the remaining streams are closed this connection will be closed automatically
    This is not implemented for HTTP/1.x.
    Parameters:
    
    errorCode - the GOAWAY error code
    
    lastStreamId - the last stream id

    Returns:
    
    a reference to this, so the API can be used fluently
  - shutdownHandler
```
