We use CFML (Railo and Adobe ColdFusion) because of its powerful scripting and high security. ColdFusion allows us to build powerful applications easily and feature rich.
Adobe® ColdFusion® application server enables developers to rapidly build, deploy, and maintain robust Internet applications for the enterprise.
Railo - or to be precise Rhylo ('Rhylo' if you say it in English, it is written as 'Railo' in German), has good compatibility with other CFML engines. Most sites can be ported to Railo with very little effort and all of the major CFML frameworks support Railo out of the box.
The CFML engine is used by thousands, from individual to government websites around the world. The engine allows high traffic websites to process without delays and provide high security services to help against hackers and attackers.
