misunderstood regex location

[dcaillibaud]

Hi,

I understood that prefix location was read, then regex location and it stops
on a ^~ match

Why with this config

      location / { 
          location ~ .+\.(js|css|ico|png|gif|jpg|jpeg|pdf|zip|html|htm)$ {
              expires 25h;
          }
      }

      location ^~ /banniere_rotative/.+\.(js|css)$ {
              expires 30d;
      }

https://ssl.sesamath.net/banniere_rotative/_writable/slides_20140503c.min.css
match the first one prefix location and not the second regex one ?

After deeper tests, I saw that 

        location /banniere_rotative/ {
            location ~ \.(js|css)$ {
                    expires 30d;
            }
        }

match but 

location ^~ "/banniere_rotative/.*\.css$" {

doesn't (inside prefix location or not)

What's the obvious mistake I made in my regex ?

Thanks
