* Introduce ActionDispatch::HostAuthorization
This is a new middleware that guards against DNS rebinding attacks by
- white-listing the allowed hosts a request can be made to.
+ explicitly permitting the hosts a request can be made to.
Each host is checked with the case operator (`#===`) to support `RegExp`,
`Proc`, `IPAddr` and custom objects as host allowances.

+* Allow applications to automatically switch connections.
+
+ Adds a middleware and configuration options that can be used in your
+ application to automatically switch between the writing and reading
+ database connections.
+
+ `GET` and `HEAD` requests will read from the replica unless there was
+ a write in the last 2 seconds, otherwise they will read from the primary.
+ Non-get requests will always write to the primary. The middleware accepts
+ an argument for a Resolver class and a Operations class where you are able
+ to change how the auto-switcher works to be most beneficial for your
+ application.
+
+ To use the middleware in your application you can use the following
+ configuration options:
+
+ ```
+ config.active_record.database_selector = { delay: 2.seconds }
+ config.active_record.database_resolver = ActiveRecord::Middleware::DatabaseSelector::Resolver
+ config.active_record.database_operations = ActiveRecord::Middleware::DatabaseSelector::Resolver::Session
+ ```
+
+ To change the database selection strategy, pass a custom class to the
+ configuration options:
+
+ ```
+ config.active_record.database_selector = { delay: 10.seconds }
+ config.active_record.database_resolver = MyResolver
+ config.active_record.database_operations = MyResolver::MyCookies
+ ```

+ # The DatabaseSelector Middleware provides a framework for automatically
+ # swapping from the primary to the replica database connection. Rails
+ # provides a basic framework to determine when to swap and allows for
+ # applications to write custom strategy classes to override the default
+ # behavior.
+ #
+ # The resolver class defines when the application should switch (i.e. read
+ # from the primary if a write occurred less than 2 seconds ago) and an
+ # operations class that sets a value that helps the resolver class decide
+ # when to switch.
+ #
+ # Rails default middleware uses the request's session to set a timestamp
+ # that informs the application when to read from a primary or read from a
+ # replica.
+ #
+ # To use the DatabaseSelector in your application with default settings add
+ # the following options to your environment config:
+ #
+ # config.active_record.database_selector = { delay: 2.seconds }
+ # config.active_record.database_resolver = ActiveRecord::Middleware::DatabaseSelector::Resolver
+ # config.active_record.database_operations = ActiveRecord::Middleware::DatabaseSelector::Resolver::Session
+ #
+ # New applications will include these lines commented out in the production.rb.
+ #
+ # The default behavior can be changed by setting the config options to a
+ # custom class:
+ #
+ # config.active_record.database_selector = { delay: 2.seconds }
+ # config.active_record.database_resolver = MyResolver
