[mod_python] redirects with cgihandler

Hi,

I'm using the cgihandler with mod_python3.0.3, Apache2.0.46 and
python2.2.3. I would like to know how I'm meant do url redirections.
My code looks something like this:

try: 
     .....
      print "Location: %s\n" % url 
except:
        pass
which works as a regular CGI script (ie. it redirects to the specified
url). It's definitely not hitting the exception and  but redirection
isn't happening either.

 Thanks in advance,
Shuying
