Methods
Modifier and Type	Method and Description
`void`	`addHeader(String name, String value)` Adds a response header with the given name and value, not overwriting any previous values which may have already been added.
`void`	`disableCompression()` Invoked to indicate that the response content is either already compressed, or is not compressable.
`String`	`encodeRedirectURL(String URL)` Encodes the URL for use as a redirect, ensuring that a session id is included (if a session exists, and as necessary depending on the client browser's use of cookies).
`String`	`encodeURL(String URL)` Encodes the URL, ensuring that a session id is included (if a session exists, and as necessary depending on the client browser's use of cookies).
`OutputStream`	`getOutputStream(String contentType)` Returns an OutputStream to which byte-oriented output may be sent.
`PrintWriter`	`getPrintWriter(String contentType)` Returns a PrintWriter object to which output may be sent.
`boolean`	`isCommitted()` Returns true if the response has already been sent, either as a redirect or as a stream of content.
`void`	`sendError(int sc, String message)` Sends an error response to the client using the specified status.

    getPrintWriter in interface Response
    
    Parameters:
    contentType - the MIME content type for the output, typically "text/html"
    
    Throws:
    
    IOException
  - encodeURL
```
public String encodeURL(String URL)
```
    Description copied from interface: Response
    
    Encodes the URL, ensuring that a session id is included (if a session exists, and as necessary depending on the client browser's use of cookies).
    
    Specified by:
    
    encodeURL in interface Response
    
    Returns:
    the same URL or a different one with additional information to track the user session
  - encodeRedirectURL
```
public String encodeRedirectURL(String URL)
```
    Description copied from interface: Response
    
    Encodes the URL for use as a redirect, ensuring that a session id is included (if a session exists, and as necessary depending on the client browser's use of cookies).
    
    Specified by:
    
    encodeRedirectURL in interface Response
    
    Returns:
    the same URL or a different one with additional information to track the user session
  - sendRedirect
```
public void sendRedirect(String URL)
                  throws IOException
```
    Description copied from interface: Response
    
    Sends a redirect to the client.
    
    Specified by:
    
    sendRedirect in interface Response
    
    Parameters:
    URL - full or partial (relative) URL to send to the client
    
    Throws:
    
    IOException
    See Also:
    Response.encodeRedirectURL(String)
  - sendRedirect
```
public void sendRedirect(Link link)
                  throws IOException
```
    Description copied from interface: Response
    
    Sends a redirect to a link.
    
    Specified by:
    
    sendRedirect in interface Response
    
    Parameters:
    link - link to redirect to.
    
    Throws:
    
    IOException
  - setStatus
```
public void setStatus(int sc)
```
    Description copied from interface: Response
    
    Sets the status code for this response. This method is used to set the return status code when there is no error (for example, for the status codes SC_OK or SC_MOVED_TEMPORARILY). If there is an error, and the caller wishes to invoke an error-page defined in the web applicaion, the sendError method should be used instead.
    
    Specified by:
    
    setStatus in interface Response
    
    Parameters:
    sc - the status code
  - getOutputStream
```
public OutputStream getOutputStream(String contentType)
                             throws IOException
```
    Description copied from interface: Response
    
    Returns an OutputStream to which byte-oriented output may be sent. Invoking flush() on the stream will commit the output.
    
    Specified by:
    
    getOutputStream in interface Response
    
    Parameters:
    contentType - the MIME content type for the output, often "application/octet-stream" or "text/plain" or one of several others
    
    Throws:
    
    IOException
  - sendError
```
public void sendError(int sc,
             String message)
               throws IOException
```
    Description copied from interface: Response
    
    Sends an error response to the client using the specified status. The server defaults to creating the response to look like an HTML-formatted server error page containing the specified message, setting the content type to "text/html", leaving cookies and other headers unmodified. If an error-page declaration has been made for the web application corresponding to the status code passed in, it will be served back in preference to the suggested msg parameter. If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.
    
    Specified by:
    
    sendError in interface Response
    
    Parameters:
    sc - the error status code
    message - the descriptive message
    
    Throws:
    
    IOException - If an input or output exception occurs
  - setContentLength
```
public void setContentLength(int length)
```
    Description copied from interface: Response
    
    Sets the length of the content body in the response; this method sets the HTTP Content-Length header.
    
    Specified by:
    
    setContentLength in interface Response
    
    Parameters:
    length - the length of the content
