Reverse proxy with form auth.

Hi friends !

I have a web site (greenhouses's environment control) on an internal Apache server. This server is not managed by us, so I can't edit file on this server.

I need to access this web site from external.

An simple URL rewrite (Reverse proxy) work :

<system.webServer><rewrite><rules><rule name="ReverseProxyInboundRule1" stopProcessing="true"><match url="(.*)" /><action type="Rewrite" url="http://192.168.0.10/{R:1}" /></rule></rules></rewrite></system.webServer>

But anybody from external can access it.

So I would like to add form authentication. I have make a simple "logon.aspx" page on my IIS7 but I not able to have form auth and URL rewrite at the same time.

The URL rewrite rules override form auth

Someone can help me ?

Thanks you
