While Coldfusion is no longer as popular as it once was, there are a large number of legacy applications built on the Coldfusion platform which still work perfectly well, and while we wouldn’t advocate it’s usage in new projects, we also wouldn’t advocate completely rewriting an existing application if there is no significant benefit to it.
We have experience in working on Coldfusion applications (both cfscript and the traditional tag based language), and have no issues with taking on new tasks on this platform.
