I figured out a way to do this, but I'm not sure it is
too elegant:

Have your output go to a string in your _call_

so replace self.write with self.result.append

and in your write_content function have the following:


Also does anyone know how to redirect the current
request to another servlet so that the current req
object is kept intact. The problem in some more
details is as follows. I have an application which
checks to see if a user is logged in through the
session. However, if the user is not logged in I want
to redirect to the login servlet with the error
message sent as part of the req object. 

I can do that by /Login?err_msg="You have to be logged
in" however then anyone can send messages to my login
screen which get displayed on the return. I'd rather
have someway (secure) of passing the err_msg
