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?
