Regular Expression Routes in Rails

Question

I am looking to create a rails route that is capable of accepting requests using a regular expression. Specifically, I need optional paths. As an example:

"(/first)?(/second)?"

Would match:

/first
/second
/first/second

But not:

/second/first

Is this possible? Thanks.

更新到Rails 3（现在正确支持REGEX路由）。
