Describe the role of the CFML engine in the ColdFusion execution model.



The CFML engine is the core component responsible for interpreting and executing ColdFusion Markup Language (CFML) code within the ColdFusion runtime environment. To understand its role, it's essential to grasp the overall ColdFusion execution model, which can be broadly divided into several stages: request reception, parsing, compilation, execution, and response generation. The CFML engine is primarily involved in the compilation and execution phases, though it interacts with other components throughout the process. When a ColdFusion server receives a request (e.g., a user clicking a link or submitting a form), the request is initially handled by the web server (like Apache or IIS). The web server then passes the request to the ColdFusion application server. The ColdFusion application server identifies the CFML page or application that should handle the request. The first step is *parsing*. The CFML engine takes the CFML code from the requested page and analyzes its syntax. This process verifies that the code is correctly formatted and identifies the diffe....
