Rails - Nov 2012 - [Rails 3.2.8] issue in regex scan

running a scan in irb is fine :

1.9.3p194 :001 > request_url = 
"http://lvh.me::3000/en/backoffice/cms-admin/site/6/pages"
 => "http://lvh.me::3000/en/backoffice/cms-admin/site/6/pages"  
request_url.scan(/^([\S]+)(backoffice\/cms-admin\/site\/)(\d+)(\/pages)$/)[0][2]
 => "6" 

however running it in my controller doesn''t gives any result :

(rdb:1) request.url
"http://lvh.me:3000/en/backoffice/cms-admin/sites/6/pages"
 site_id = 
request.url.scan(/^([\S]+)(backoffice\/cms-admin\/site\/)(\d+)(\/pages)$/)[0][2]
NoMethodError Exception: undefined method `[]'' for nil:NilClass

(rdb:1) 
request.url.scan(/^([\S]+)(backoffice\/cms-admin\/site\/)(\d+)(\/pages)$/)
[]
#  empty result 

the url is the same, the regex also ..  what''s wrong with performing
the
scan in a Rails app ?

thanks for feedback
