iis7 URL redirected cfm page does not load well / connection reset

I am using IIS7.5 and Coldfusion 10 update 10. Furthermore i configured IIS to execute a cfm page when a file is not found (404).

This CFM page then will show an custom error. It looks like the page will only loads 1.6 Kb data.

In CF 9 this config works fine, but in CF10 the page will not load well. Sometimes only a few bytes are sent. Also i've got mesages from my browsers that the connection is resetted by peer.

I've seen much questions about this issue, but no sollution till now... Does anyone have a solution for this issue?

Thanks Sam
