[Zope] Strange issues at string operations with request variables

[Jaroslav Lukesh]

Hi,

I was try the python script, but no success.

The final cut (as Murphy law says):
<dtml-call 
expr="RESPONSE.redirect('http://www.otherdomain.com/path/to/document', 
status=301)">

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

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' + 
URLPATH0)">
<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 
loop.

<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com' + 
PATH_TRANSLATED)">
<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com' + 
_.str(_['URLPATH1']))">
<dtml-call "REQUEST.set('redirect_URL', 'http://www.otherdomain.com')">

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

<dtml-call "REQUEST.set('redirect_URL', 
URL.replace(BASE0,'http://www.otherdomain.com')[0])">
<dtml-call "REQUEST.set('redirect_URL', 
URL.replace(_.string.split(HTTP_HOST,':')[0],'www.otherdomain.com')[0])">


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,
