Fwd: nginx.conf + Location + regular expression

[fx.juhel at free.fr]

Hello nginx DEV TEAM ! How are you ?

I would like to know how can I do to detect this type of directory name with regexp : (Guid  8-4-4-4-12) => “be93d4d0-b25b-de94-fcbb-463e6c0fe9cc”

How can I use $reg_exp in location
I do this : 

set $reg_exp "[0-9a-fA-F]{8}?-[0-9a-fA-F]{4}?-[0-9a-fA-F]{4}?-[0-9a-fA-F]{4}?-[0-9a-fA-F]{12}"; 

location ~ ^/locale/Project/Documents/(reg_exp)/(?<document>.*)$ {

}


Thank you very well for your reply
