IIS URL Rewrite Regular Expressions

Question

I am new writing IIS URL Rewrite regular expressions and have put together the following regular expression.

^(.*/?\.?)([^/]*)$

This currently matches the following paths

1. home
2. home.
3. home.aspx
4. home/about
5. home/about.aspx and so forth.

Is this the most efficient way to rewrite URLs? Is there a better way?
