  - isResponseAvailable
```
public boolean isResponseAvailable(int timeout)
                            throws java.io.IOException
```
    Deprecated.
    
    Description copied from interface: HttpClientConnection
    
    Checks if response 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:
    
    isResponseAvailable in interface HttpClientConnection
    
    Parameters:
    
    timeout - the maximum time in milliseconds to wait for data
    
    Returns:
    
    true if data is available; false if there was no data available even after waiting for timeout milliseconds.
    
    Throws:
    
    java.io.IOException - if an error happens on the connection
  - sendRequestHeader
```
public void sendRequestHeader(HttpRequest request)
                       throws HttpException,
                              java.io.IOException
```
    Deprecated.
    
    Description copied from interface: HttpClientConnection
    
    Sends the request line and all headers over the connection.
    
    Specified by:
    
    sendRequestHeader in interface HttpClientConnection
    
    Parameters:
    
    request - the request whose headers to send.
    
    Throws:
    
    HttpException - in case of HTTP protocol violation
    
    java.io.IOException - in case of an I/O error
  - sendRequestEntity
```
public void sendRequestEntity(HttpEntityEnclosingRequest request)
                       throws HttpException,

```
    Deprecated.
    
    Description copied from interface: HttpClientConnection
    
    Sends the request entity over the connection.
    
    Specified by:
    
    sendRequestEntity in interface HttpClientConnection
    
    Parameters:
    
    request - the request whose entity to send.
    
    Throws:
    
    HttpException - in case of HTTP protocol violation
    
    java.io.IOException - in case of an I/O error
  - flush

```
    Deprecated.
    
    Description copied from interface: HttpClientConnection
    
    Writes out all pending buffered data over the open connection.
    
    Specified by:

```
public HttpResponse receiveResponseHeader()
                                   throws HttpException,
                                          java.io.IOException
```
    Deprecated.
    
    Description copied from interface: HttpClientConnection
    
    Receives the request line and headers of the next response available from this connection. The caller should examine the HttpResponse object to find out if it should try to receive a response entity as well.
    
    Specified by:
    
    receiveResponseHeader in interface HttpClientConnection
    
    Returns:
    
    a new HttpResponse object with status line and headers initialized.

```
    Deprecated.
    
    Description copied from interface: HttpClientConnection
    
    Receives the next response entity available from this connection and attaches it to an existing HttpResponse object.
    
    Specified by:
    
    receiveResponseEntity in interface HttpClientConnection
    
    Parameters:
    
    response - the response to attach the entity to
    
    Throws:
    
    HttpException - in case of HTTP protocol violation
    
    java.io.IOException - in case of an I/O error
  - isStale
```
public boolean isStale()
```
    Deprecated.
    
    Description copied from interface: HttpConnection
    
    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 HttpConnection
    
    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
  - getMetrics
```
public HttpConnectionMetrics getMetrics()
```
    Deprecated.
    
    Description copied from interface: HttpConnection
    
    Returns a collection of connection metrics.
    
    Specified by:
    
    getMetrics in interface HttpConnection
    
    Returns:
    
    HttpConnectionMetrics
