I was try the python script, but no success.

The final cut (as Murphy law says):

1. At Zope 2.10.13 redirect to samedomain which cause loop, not to the 

2. At Zope 2.7 this redirect is redirected to otherdomain which is expected. 
At Zope 2.7 I was not test redirect with PySript.

So I use redirect to home page.

What I would do is do this with a python script instead of DTML. You will 
find this kind of stuff is much simpler with a python script you just call 
from DTML

something like

REQUEST['redirect_URL'] = 'http://www.otherdomain.com' + REQUEST.URLPATH0

Hi all,

I have discovered strange issues with all request variables. Here are 
examples only, but I was try all useable variables in the REQUEST.

I want to use redirect to another server with same relative link, but 
different domain,some like that:

<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com' + 
<dtml-call expr="RESPONSE.redirect(_.str(redirect_URL), status=301)">

It does not work even if I make obstructions for request variables like 
_.str(), _[''] etc.

In cases below variable 'redirect_URL' seems OK, but redirect goes into 

<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com' + 
<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com' + 
<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com')">

In cases below variable 'redirect_URL' = 'h'.

<dtml-call "REQUEST.set('redirect_URL', 
<dtml-call "REQUEST.set('redirect_URL', 

I was try different (very old) Zope, but result is the same.

It is possible my uncorrect handle with request variables, but how to handle 
correct with them?

Many thanks,

J. Lukesh
