<P>
This function is functionally equivalent to the standard library
<tt class="module">cgi</tt> <tt class="function">parse_qs</tt>, except that it is written in C and is
much faster.
<P>
Parse a query string given as a string argument (data of type
<span class="mimetype">application/x-www-form-urlencoded</span>). Data are
returned as a dictionary. The dictionary keys are the unique query
variable names and the values are lists of values for each name.
<P>
The optional argument <var>keep_blank_values</var> is a flag indicating
whether blank values in URL encoded queries should be treated as blank
strings. A true value indicates that blanks should be retained as
blank strings. The default false value indicates that blank values
are to be ignored and treated as if they were not included.

Parse a query string given as a string argument (data of type

returned as a list of name, value pairs.

<dd>
This is a convenience function to redirect the browser to another
location. When <var>permanent</var> is true, <tt class="constant">MOVED_PERMANENTLY</tt>
status is sent to the client, otherwise it is
<tt class="constant">MOVED_TEMPORARILY</tt>. A short text is sent to the browser
informing that the document has moved (for those rare browsers that
do not support redirection); this text can be overridden by
supplying a <var>text</var> string.
<P>
If this function is called after the headers have already been sent,
an <tt class="exception">IOError</tt> is raised.
<P>
This function raises <tt class="exception">apache.SERVER_RETURN</tt> exception to
abandon any further processing of the handle. If you do not want
this, you can wrap the call to <tt class="function">redirect</tt> in a try/except
block catching the <tt class="exception">apache.SERVER_RETURN</tt>.
