[Zope] Passing a list through a url

[belen@netcom.no]

I need to pass a list through a url. Is there anyway to do it?

 I receive a list from a DTML document and I need to pass it again to a 
method. I have verified that the intermediate document receives a list 
but when the last method retrieves it the type is string. I can cast it 
to be a list by :

<dtml-call "RESPONSE.redirect('Destination?myList:list'+`myList`)"> 

but  <dtml-var mylist> renders ["[x]"] where I have a list containing a 
string.

Any ideas?

Thanks
