Is it possible to make this product redirect whole 
sub-trees? I'm migrating
a Zop1 site using cgi under IIS to Zope2 using ZServer. I 
want to redirect
all the "/cgi-bin/zope.exe/(.*)" queries to "/\1" using the 
grouping syntax.
since I'm not using apache I can't use mod_rewrite so this 
is the only
option I can think of at the moment and I can't upgrade 
until I have the
redirection in place.
I can do the substitution no prob by changing after line 95 like so
for k in self.Mappings.keys():
        m = re.match(k, Name)
        if m:
          Name = re.sub(k, self.Mappings[k], Name)
But "Name" is not the remainder of the url :(
I believe there is a redirection product doing just that:
http://www.zope.org:18200/Members/astaubo/Redirector
Opps, didn't make myself clear. The Redirector product is 
what I'm using and it doesn't do that. It redirects only 
objects in one folder not and entire subtree.
Ok, here is the patch that will allow the redirection of subtrees. Whats
more it does reg-exp substitutions. The __bobo_traverse__ method in
Redirector.py should look like this.

  def __bobo_traverse__(self, REQUEST, Name = ''):
  
    if Name[:6] != 'manage':
      import ExtensionClass
      class doTraverse(ExtensionClass.Base):
         def __init__(self, path, Mappings, Target, HardMap):
            self.path = path
            self.Mappings = Mappings
            self.Target = Target
            self.HardMap = HardMap
         
         def __bobo_traverse__(self, REQUEST, Name = ''):
            self.path = self.path + '/' + Name
            return self.__class__(self.path, self.Mappings, self.Target,
self.HardMap)
            
         def __call__(self, REQUEST):
            path = self.path
            if REQUEST['QUERY_STRING']:
              path = path + "?" + REQUEST['QUERY_STRING']
            for k in self.Mappings.keys():
              if re.match(k, path):
                 path = re.sub(k, self.Mappings[k], path)
                 break
            else:
              if self.HardMap:
                 raise 'Redirect', self.Target
            def Merge(Target, Url):
              if Url[:5] == 'http:' or Url[:4] == 'ftp:':
                 return Url
              else:
                 return Target + Url
            raise 'Redirect', Merge(self.Target , path)
            
      return doTraverse(Name, self.Mappings, self.Target, self.HardMap)
     

    if hasattr(self, 'aq_base'):
      b = self.aq_base
      if hasattr(b, Name):
        return getattr(self, Name)
    try:
      return self[Name]
    except:
      return getattr(self, Name)
