I didn't even run Apache. I used VHM mappings directly:
*.example.com/Example, for example.

And it **DOES** happen with this simple setting. I don't know exactly when.

Yes, I meant exactly that ;-)

I did:

    security.declarePrivate( '_getObjectURL' )
    def _getObjectURL( self, ob ):
        """
            Return Object URL
        """
        
        path = list( ob.getPhysicalPath() )
        path = path[ path.index(
self.getNeoPortalElementContainerCatalog().getId() )+1: ]
        
        # make paths acquisition-safe
        while ( self.getNeoPortalElementContainerCatalog().getId() in path
):
            path.remove( self.getNeoPortalElementContainerCatalog().getId()
)
        
        return '/'+ '/'.join( path )

Just removing every instance of the container's id in the path looked
simpler :-)

I'll try your idea.

Thanks.

All the best,
