The runtime handles HTTP requests through a well-defined lifecycle, with full support for REST, sessions, CSRF, SSE, and both MiniServer (dev) and CommandBox (production) deployment. For a deep dive into multi-app isolation, descriptor discovery, and advanced `Application.bx` patterns, see the [`application-descriptor`](../application-descriptor/SKILL.md) skill. ## Application.bx `Application.bx` lives at the web root and configures the entire application: ```boxlang // Application.bx class { // Application settings this.name = "MyApp" this.sessionManagement = true this.sessionTimeout = createTimeSpan( 0, 2, 0, 0 ) // 2 hours this.applicationTimeout = createTimeSpan( 1, 0, 0, 0 ) // 1 day this.setClientCookies = true // Java classpath additions this.javaSettings = { loadPaths: [ "lib/" ], loadColdFusionClassPath: false, reloadOnChange: false } // Datasource defaults this.datasource = "mainDB" // --- Lifecycle Events --- // Fires once when the application first starts boolean function onApplicationStart() { application.version = "1.0.0" application.config = loadConfig() return true } // Fires before every request boolean function onRequestStart( required string targetPage ) { // Auth
