[Zope] setting cookies in a python script? (OmniWeb issue)

[Marc Dumouchel]

On our Zope site (www.su.ualberta.ca), we have a splash page 
that lets users choose which version of the site they want to 
see.  That page has links to two methods, each of which set two 
cookies:

splash --> gets set to 'yes', this prevents the user from 
encountering the splash page on subsequent visits.

bandwidth --> gets set to either 'high' or 'low', depending on 
which method they click through to.

The code for one of the methods, "setBandwidthHigh", (the other 
is almost identical):

<dtml-call "RESPONSE.setCookie('bandwidth', 'high', 
domain='su.ualberta.ca', expires='Wed, 19 Feb 2020 14:28:00 
GMT')">
<dtml-call "RESPONSE.setCookie('splash', 'yes', 
domain='su.ualberta.ca', expires='Wed, 19 Feb 2020 14:28:00 
GMT')">
<dtml-call "RESPONSE.redirect('index_html')">


The problem I have is with a browsers such as OmniWeb 4.0.5 (Mac 
OS X).  OmniWeb adds the path of the method to the cookie, so 
the cookie gets listed in this form:
domain:  su.ualberta.ca
path: /setBandwidthHigh
name: bandwidth
value: high

Other browsers simply list the path as /, and work just fine.  
Omniweb doesn't work, because when index_html checks for the 
cookie, the cookie as listed doesn't show up because the path is 
too specific.  Doing a <dtml-var REQUEST> shows no cookie 
entries under OmniWeb (unless I include the path in the URL- 
e.g. "www.domain/setBandwidthHigh/samplepage/".  Instead, the 
splash page just comes back up.

I'm still pretty new to Python, but I was thinking that if I put 
a form button on the page to select the site version, I could 
have a Python script execute when it clicked that set the cookie 
properly in OmniWeb (i.e., with a path of '/').  Can I set 
cookies from within a Python script?  Any other suggestions to 
solve my problem?
