 ### Dependency Injection & Octane
 
 Since Octane boots your application once and keeps it in memory while serving requests, there are a few caveats you should consider while building your application. For example, the `register` and `boot` methods of your application's service providers will only be executed once when the request worker initially boots. On subsequent requests, the same application instance will be reused.
