多个Symfony 2防火墙中的多个提供商：如何避免路由冲突？

I'm having a small problem with firewalls routes conflicting. I expected Symfony to handle them in order, but it's not:

security:
    firewalls:
        first_area:
            pattern:    ^api/
            http_basic:
                realm: "Secured Demo Area"
                provider: in_memory
        second_area:
            pattern:    ^/
            http_basic:
                realm: "Secured Demo Area"
                provider: in_database

This is conflicting, so i can't separate areas to have different providers.

try pattern: ^/api/ for first firewall (added slash)
