i heard of cold fustion, i heard it takes like half the amout of code as a normal C code would take.
I have been using it almost exclusively for about 9 years now and it is a very effective rapid development tool. While my web programmers do most of that work in my office, they are experienced php,perl and ASP developers (one with 15+ years) and his usually assessment is writing web apps in CF takes anywhere from 1/10th to 1/2 the time it would take him in ASP or php. It's only drawback is that it does cost money for the server-side engine and most hosting providers will usually add a couple bucks a month for the service, however that is very quickly made up on the hundreds of man hours saved in development costs. It is also VERY easy for web designers and HTML guys to pick up even with little or no programming experience.
