parseQueryString</H3>
<PRE>
public static java.util.Hashtable <B>parseQueryString</B>(java.lang.String&nbsp;s)</PRE>
<DL>
<DD><B>Deprecated.</B>&nbsp;<DD>Parses a query string passed from the client to the
 server and builds a <code>HashTable</code> object
 with key-value pairs. 
 The query string should be in the form of a string
 packaged by the GET or POST method, that is, it
 should have key-value pairs in the form <i>key=value</i>,
 with each pair separated from the next by a &amp; character.

 <p>A key can appear more than once in the query string
 with different values. However, the key appears only once in 
 the hashtable, with its value being
 an array of strings containing the multiple values sent
 by the query string.
 
 <p>The keys and values in the hashtable are stored in their
 decoded form, so
 any + characters are converted to spaces, and characters
 sent in hexadecimal notation (like <i>%xx</i>) are
 converted to ASCII characters.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>s</CODE> - a string containing the query to be parsed
<DT><B>Returns:</B><DD>a <code>HashTable</code> object built
 			from the parsed key-value pairs
<DT><B>Throws:</B>
<DD><CODE>java.lang.IllegalArgumentException</CODE> - if the query string 
						is invalid</DL>

<DL>
<DD><B>Deprecated.</B>&nbsp;<DD>Parses data from an HTML form that the client sends to 
 the server using the HTTP POST method and the 
 <i>application/x-www-form-urlencoded</i> MIME type.

 <p>The data sent by the POST method contains key-value
 pairs. A key can appear more than once in the POST data
 with different values. However, the key appears only once in 
 the hashtable, with its value being
 an array of strings containing the multiple values sent
 by the POST method.

 <p>The keys and values in the hashtable are stored in their
 decoded form, so
 any + characters are converted to spaces, and characters
 sent in hexadecimal notation (like <i>%xx</i>) are

public static java.lang.StringBuffer <B>getRequestURL</B>(<A HREF="../../../javax/servlet/http/HttpServletRequest.html" title="interface in javax.servlet.http">HttpServletRequest</A>&nbsp;req)</PRE>
<DL>
<DD><B>Deprecated.</B>&nbsp;<DD>Reconstructs the URL the client used to make the request,
 using information in the <code>HttpServletRequest</code> object.
 The returned URL contains a protocol, server name, port
 number, and server path, but it does not include query
 string parameters.
 
 <p>Because this method returns a <code>StringBuffer</code>,
 not a string, you can modify the URL easily, for example,
 to append query parameters.

 <p>This method is useful for creating redirect messages
 and for reporting errors.

<DT><B>Parameters:</B><DD><CODE>req</CODE> - a <code>HttpServletRequest</code> object
			containing the client's request
<DT><B>Returns:</B><DD>a <code>StringBuffer</code> object containing
