Hello everybody!

I have a Windows 2016 DCE with IIS 10 with 2 sites binded on different IP and port 80.
Each of this sites use IIS Reverse proxy (ARR) to site placed on VM (Hyper-v).
The VM has same OS - 2016 DCE, IIS 10 and installed Lucee v.

Sites on VM separated by ports 80 and 81.

It looks like: => =>

The problem is when I first time open one of sites I can see the page of choosed site. When I trying to open next site the show me same page from first site.

When I change default document to htm. It works perfect. But when I rename back to cfm, I see the same page. Help somebody!
