Passing an argument to a node causes 404 On my page I have a block that reads a variable in the URL.  The page that it reads it on is a node.  When I pass an argument through the URL to the node, it causes a 404 error. ex:

www.example.com/experience //This is the node, it works
www.example.com/experience/asia //Asia is the argument, I get 404


I've tried configuring the URL Alias to "experience/*", but this obviously didn't work and only accepts '*' as the argument.  What do I need to configure to make this work?

I've heard of some modules that automatically add the aliases to the configuration table, but I would prefer a more straight-forward solution.
There are modules to accept subpath aliases.

If you're on Drupal 6 then look into the subpath_alias module. 

Drupal 7 has subpathauto which does the same thing.

What they do is expand Drupal's path matching to work with subpaths, so no extra aliases are added. I've used it in the past when embedding views within nodes and it worked a treat.

So if you have node/4 aliased to path/test then it will recognise path/test/argument as node/4/argument
