CFM running from html

To expand on Owain's answer.

In order to get your CFML code executed, the web server (IIS, Apache, etc) needs to know what requests to pass to the ColdFusion Application Server.  By default, the web server is usually configured to pass files with ColdFusion extensons (cfm, cfc, cfr, etc)  to the ColdFusion Applicaiton Server.  It is quite possible to configure any extension you want the web server to pass to ColdFusion, such as htm, html, css, js, etc.  This would allow you to put CFML code into an html file and have it executed by the ColdFusion application server.

Other alternatives you can use so that you do not have to change the URLS of existing HTML files to convert them to using CFML.

1) You could use inline frames inside the HTML page that requests CFML content from another file.

2) You could set up 301 Permanant redirect responses (usually in the web server) for the HTML pages that direct requests to the new CFML pages.

Yup, you'll need to change the ISAPI filter on the IIS website to also pass .html files to CF, as well as the normal .cfm, .cfml etc.
