               throws java.io.IOException</PRE>
<DL>
<DD>Sends an error response to the client using the specified
 status clearing the buffer.  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. 

 <p>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.<DD><DL>

<PRE>
public void <B>sendRedirect</B>(java.lang.String&nbsp;location)
                  throws java.io.IOException</PRE>
<DL>
<DD>Sends a temporary redirect response to the client using the
 specified redirect location URL.  This method can accept relative URLs;
 the servlet container must convert the relative URL to an absolute URL
 before sending the response to the client. If the location is relative 
 without a leading '/' the container interprets it as relative to
 the current request URI. If the location is relative with a leading
 '/' the container interprets it as relative to the servlet container root.

 <p>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.<DD><DL>
