Soft Lock

The soft lock interacts at the Symfony2 kernel.request event with a priority of 255 that should be the max priority. The listener stop the event propagation in case of lock and replies with the maintenance page.

The command is very simple:

app/console corley:maintenance:soft-lock on/off

Configuration

You can configure a list of allowed paths and a list of IP addresses in order to exclude the soft lock mode during the maintenance.

corley_maintenance:
    whitelist:
        paths:
            - ^/_
            - ^/admin
        ips:
            - 127.0.0.1

The previous configuration allows any connections from 127.0.0.1 and allows to all users to visit any pages that start with: /_ or /admin
