iis - ISAPI Rewrite wont proxy the root folder -

I was not sure whether this is a ServerFault question or stack overflow, so I'm going to ask it here first.

While using ISAPI rewrite (Helian Tech), I can not find a root directory proxy

Subtitles will work on other servers, but only plain old '/' work

Here is a copy of my .htaccess

  # helicon ISAPI_revinated configuration file # version 3.1.0.69 rewritebase / rewriter (. +) Rewriting engine at http: / / Internalsite / $ 1 [P] & lt; Helicon & gt; ProxyConnect Time 120 & lt; / Helicon & gt;  

There is no default document in the InternalSite, because it uses mod_rewrite (wordpress).

but just plain old '/' will not work

This can be because you have to type the Sense again and then (because you do not have any more characters yet please try to fix your configuration like this:

  RewriteBase / RewriteRule (. *) On the re-engineer engine http: // internalsite / $ 1 [P]
