Drupal multiple node url aliases Is it possible to take a field from my node and create a url alias from the content of that field?

Say I have a node type article. This gets its normal url via pathauto, but I also wish to be able to create a short url so I can go to example.com/LS and I will be redirected to the node.

How can this custom short url be created automatically?
When you create a node they will always use the url node/[nid].

You can use the path auto module to create an url alias for the standard node. Path auto uses the token module to create the url alias for the nodes.

What you can do, is to create a token for the value of the field, and then setup path auto to use the contents of the field when creating the url alias.

Another thing you could do is to use the ShURLy module, to actual create short urls. You could make a custom module where you created or update the short url for the node when saved, and let ShURLy handle the redirects.
