CFWebstore requires a ColdFusion server to run. What exactly is ColdFusion? ColdFusion is an application server currently owned and developed by Adobe. It takes the code you write, using a tag-based language called CFML, to create dynamic, database-driven web sites. It is similar to other popular scripting server-side languages such as ASP.Net and PHP, but is often the easiest and fastest to code in. You don't need to know ColdFusion to get started with CFWebstore, but it certainly helps, particularly if you plan to do any custom coding. The more you work with the software though, the more you'll learn about ColdFusion and how easy it is to use! It's a great language to learn if you are mainly a web site developer and new to programming languages. Currently CFWebstore supports ColdFusion MX 6.1 and later servers, as well as BlueDragon 6.2+, Open Source BlueDragon and Railo 3.0 and up.
