Handler won't receive request after URL-Rewrite.

I'm running URL-Rewrite 7.2.1993 on Windows 2019 Server (IIS 10) and Bluedragon 7.1.1, which is a ColdFusion Markup Language (CFML) engine comparable to Adobe Systems's ColdFusion.

Everything works fine, but if I use the "URL Rewrite"-Modul, the referenced Coldfusion-Page is interpreted as HTML.
This only happens with the "Rewrite"-Function, the "Redirect"-Function works very well. It seems, that the Bluedragon handler won't receive the request after URL-Rewrite.

I changed the sorting in "Handler mappings" but it did not help.

On an other system (Windows 2008 R2, IIS 7.5) with URL Rewrite 7.2.2 and Bluedragon 7.1.1, everything works fine.

Can someone help?
