In my case I do not care about crawler penalty.
I have multilingual site with menu. I use Path module for URL aliases. The URL aliases are language-specific.
I need to create two menu items with different URL aliases but both links have to render the same content node. I need to do it only for one particular node with known node id, so any hardcoded/hack solution is welcomed.
I'm just thinking about such hack solution: I can create some new fake node, set the proper url alias and add menu item for this node. When Drupal is about rendering of this fake node then I'd interrupt the rendering in the code and just render the desired known node.
Is it possible? If so, how can I achieve this?
