Can you edit a Coldfusion website using Kompozer

ColdFusion is both an application server and a language CFML.

You can edit CFML files with any text editor, Dreamweaver, Bolt, and CFEclipse are three popular choices.  But one can use notepad or VI if one wants to.

To run the CFML pages, you need an server running the ColdFusion applicaiton server.  If you are working on an existing site, then that site must be running the ColdFusion server.  If you would like one set up on your workstation, the developer version is free and can be downloaded from www.coldfusion.com.

You need Cold Fusion Software to run Cold Fusion pages.  You can get a developer's edition for free.

To edit cfml pages, you can use any text editor.  If Kompozer has a code view, you can use it.  If it's strictly design view, probably not.  I use Dreamweaver, which is expensive.  Another popular code editor is Eclipse.  I don't know if it's free.
