A Fusebox 4.1 application consists of Circuits. A circuit corresponds to the directory of the application. There are one or more fuseactions in each circuit. A fuseaction is a request handeller. Fuseaction executes one or more fuses. Fuses are individual CFML pages in ColdFusion.

Fusebox requests are made of the server through a central controller called index.cfm. This is the central channel through which all requests pass and that contains several fuseaction methods.

Listing 1

index.cfm?fuseaction=document.login

Here, central controller is index.cfm and it receives the fuseaction message of document.login.

Document is the circuit name and login is the fuseaction name.
