IIS as Reverse Proxy für Apache Tomcat

Hello,

this morning I configured an IIS webserver as a reverse proxy with rewrite 2.0 for java application "BlueAnt" running at apache tomcat.

It works fine, except that some URLs are not forwarded by reverse proxy.

https://blueant.mydomain.tld/blueant//psap/Aktuelle+Ansicht.csvfor example comes with IIS 404 error page. It seems like non-html requests like file-downloads are not forwarded by rewrite module.

Is there any hint how to fix this.

I'm running IIS on Win Server 2012 R2.

Thanks for yor help :-)
