Regex in .htaccess

[wpt394]

So I know this may not be in php exactly, but I think it's pretty close....

 

I have a website on which I've been using the Rewrite Rule in my .htaccess file to make dynamic urls appear static.

 

For example, at first I would take a url that looked like:

 

http://www.example.com?variable=two%20words  (call this Version 1)

 

and transform it to this:

 

http://www.example.com/two%20words  (call this Version 2)

 

 

But....now I've switched the spaces (%20) to dashes (-) so the urls look like

 

http://www.example.com/two-words (Version 3)

 

 

The question is, how do I use a 301 redirect to make the version 2 urls redirect to the version 3 urls?  Thanks for any help.

Unless I'm wrong, I'm pretty certain that you won't be able to do this. If you find a solution, I am very curious to see what it is.
