We use Apache Reverse Proxy Server to forward requests to our backend IIS server.

When we make a request to backend resource via the reverse proxy server, we are getting:

404 - File or directory not found

How can we resolve this?
The resource is not available on the backend server.

You have to confirm that you can access the resource directly from the reverse proxy host via the browser(without passing through the reverse proxy server)
Configure the backend server correctly so resource can be accessed directly
