public java.lang.String <B>encodeURL</B>(java.lang.String&nbsp;url)</PRE>
<DL>
<DD>Encodes the specified URL by including the session ID in it,
 or, if encoding is not needed, returns the URL unchanged.
 The implementation of this method includes the logic to
 determine whether the session ID needs to be encoded in the URL.
 For example, if the browser supports cookies, or session
 tracking is turned off, URL encoding is unnecessary.
 
 <p>For robust session tracking, all URLs emitted by a servlet 
 should be run through this
 method.  Otherwise, URL rewriting cannot be used with browsers
 which do not support cookies.<DD><DL>

<DL>
<DD>Encodes the specified URL for use in the
 <code>sendRedirect</code> method or, if encoding is not needed,
 returns the URL unchanged.  The implementation of this method
 includes the logic to determine whether the session ID
 needs to be encoded in the URL.  Because the rules for making
 this determination can differ from those used to decide whether to
 encode a normal link, this method is seperate from the
 <code>encodeURL</code> method.
 
 <p>All URLs sent to the <code>HttpServletResponse.sendRedirect</code>
 method should be run through this method.  Otherwise, URL
 rewriting cannot be used with browsers which do not support
 cookies.<DD><DL>
