Coldfusion master-page ?

I am an asp.net programmer but I am using coldfusion now and my question is.. whats the best method to do a coldfusion masterpage similar to asp.net ? where all the page features are the same except the title and maincontent ...

CF does not have a built-in analog of master page. You have a few options:

The most basic is to use cfinclude to include common headers, footers, etc.

The next is to create a layout file that has placeholder variables in it. You then generate your content into those variables (possibly using cfsavecontent).

All of the popular MVC frameworks (ColdBox, Model-Glue, FW/1, etc.) include layout and templating features. So the third option (and the one I would recommend) would be to choose one of those to use.
