At last i found it… what i need is just \d in front of the regex…
Hu?
Are you actually talking to Glen while replying my mail,
or did I miss something obvious in the regex above?

sorry, i was talking to glen… no offense:-)
I think i’ve confused 
What i want is
http://www.mydomain.com/$number/title
i need to get that $number then rewrite it to
http://app.mydomain.com/redirect/$number
I’ve read about regex, and seems that’s not the right thing to do
