parse .htm with coldfusion 2016?

I have just switched over to coldfusion 2016 on windows 2012 with IIS 8 and can't get the server to process .htm pages as .cfm. Just like in previous versions, I have added the following to the web.xml file with no success.

<servlet-mapping id="coldfusion_mapping_

        <servlet-name>CfmServlet</servlet-name>

        <url-pattern>*.htm/*</url-pattern>

    </servlet-mapping>

    <servlet-mapping id="coldfusion_mapping_89">

        <servlet-name>CfmServlet</servlet-name>

        <url-pattern>*.htm</url-pattern>

    </servlet-mapping>

This worked fine for coldfusion 9 and 10, but I can't find any documentation or posts with a solution for 2016. Any help would greatly be appreciated.
