PUT/PATCH request body being lost on Windows Server, IIS 8... but not with built-in web server

acf-bug-check.md

When I run the following with ColdFusion's built-in web server, the content of the request shows the request body

When I run it on a Windows Server, running IIS 8, the request body is empty. That is, the body of the PUT or PATCH request is lost. POSTs are handled without issue.

Also, it doesn't matter if the PUT/PATCH originates from ColdFusion or from an external source, like Postman; the result is the same.

In both cases, I'm running ACF 11.
