map.page ‘:sex/:word’, :controller =\> ‘say’,  
:requirements =\> { : sex =\>/girl|boy/ }

So this works fine:

[http://mypage.com/say/boy/hello](http://mypage.com/say/boy/hello)

also this:

[http://mypage.com/say/girl/hello%20world](http://mypage.com/say/girl/hello%20world)

but this:

[http://mypage.com/say/girl/hello.world](http://mypage.com/say/girl/hello.world)

returns: Error 404 The page you were looking for doesn’t exist.

How can I fix this?

I had a route like this once where :code was a series of numbers and  
periods. The below made it work.

```
 r.foo_detail '/foo/:code/:title/detail',
                     :action => 'detail',
                     :requirements => { :code => %r([\d.]+) }

```
