I can't go into details but it's a site similar to travelocity.com and expedia.com. It's a full travel site where you can book flights, hotels, cars, cruises and travel packages. There isn't anything I cannot do in Cold Fusion that I couldn't do in ASP, Java, PHP or .NET. I am experienced in all these languages and they all do practically the same thing. Some are easier to do than other but in the end they all do the same thing. Some people may have a different opinion on this but I feel it's the knowledge of the programming language and how good you really are.
Some programmers prefer Cold Fusion and ASP and other prefer (mostly readers here) prefer PHP vs. ASP. It's all about the language you learned and feel comfortable with. But IMO it's all the same. Some just cost more than others to host and maintain.
It's a powerful programming language. It's not that much different than ASP, Java, PHP or .NET. It's just another programming language.
Here are some links to some resources.
