Using ColdFusion

There are currently four versions or editions of ColdFusion:

• ColdFusion Express. This is available for free. It's used to introduce you to the ColdFusion development environment. It supports only a subset of CFML capabilities and provides limited database support.

• ColdFusion Professional. This edition allows complete access to the CFML language, complete database support, administration, and complete security support.

• ColdFusion Enterprise. This has the complete functionality of ColdFusion Professional, as well as server clustering, native database drivers for certain databases, and complete sandbox security for multiple-site hosted environments.

• ColdFusion Single-User. This is a single-user version of ColdFusion Enterprise. It comes bundled with ColdFusion Studio and limits access to one IP address per session.
