D6: Create a new template for a specific url of node type page I'm trying to create a completely different template for a page I have set up at:

http://www.example.com/my_page

I thought I just added a new node tpl page (node-my_page.tpl.php), but that doesn't appear to be working. What's the trick?
What you're looking for are template suggestions. If you want to change the page layout (regions, general html) use template suggestions for page.tpl.php. OTOH, if you want to change the node layout (the .node div and whatever is within), use template suggestion for node.tpl.php.
