[Zope] - Using external method to set/test cookies, test request vars, set vars?

[Brad Clements]

I'm trying to develop an external method that must do the following:

1. check for the existance of a request.cookie
2. set a reply cookie
3. check for variables in the query string

Optionally, I'd like to be able to "set" a variable in an external method 
that could later be tested in DHTML, though this isn't quite as important.

However even the most simple external method is giving me an error, 

read-only buffer, class

from line 266 of ExternalMethod.py

Does anyone know what this error means?

Is it going to be possible to do items 1 through 3 above in an external 
method? What about item 4? (I could do REQUEST.set() perhaps)

Maybe I'm not importing all the modules I need to.. Which modules do I 
need to get at REQUEST and REPLY?

We must come down from our heights, and leave our straight 
paths, for the byways and low places of life, if we would 
learn truths by strong contrasts; and in hovels, in forecastles, 
and among our own outcasts in foreign lands, see what has been 
wrought upon our fellow-creatures by accident, hardship, or vice.
