rebol server pages on IIS?

Can anyone offer any advice on configuring Maarten's erebol.r Rebol Server Page script on IIS? I have added an association with .rhtml to REBOL.exe, and I get the REBOL startup banner returned with the obligatory BAD HTTP HEADER message from IIS. I've used REBOL for CGI before, so I know about -cs %s %s , but that doesn't seem to work. Regards, Gavin.

Ok...so I got it to work. I guess I made the mistake of assuming that erebol.r was a plug-and-play script. I should have spent more time inspecting erebol.r first. If I had of been completely alert at the time, I would have noticed that erebol.r just defines a function that can be used for rebol server page processing. So, I had to add a line of code the to end of erebol.r to fetch the document url passed in from ISS into system/options/args/1, read it, and pass it to erebol.r. My IIS config is now just the standard rebol.exe -cs %s %s. Sorry to bother. Gavin.
