I have this IIS7.5 with ARR installed on and configured as a reverse proxy to another server which is running IIS7.

On this IIS7.5 I have ASP.NET 4 applications and simple websites installed.

Since configuring a farm on this IIS7.5 running it as a reversed proxy, the local application doesn't run with this error message:

502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.

Will it be possible to run both local application and routing (reverse proxy) at the same time on this IIS7.5 or should I give up and move the applications to another server?
