Hi Lewis

M0n0 does have SPF. What you are looking for is some kind of 
application/protocol specific proxy. I would run the Apache webserver on 
some high port, only listening on and then implement a Squid 
Caching server running in transparent mode.... aargh but this won't be 
possible on Win2K.

I don't think this is something you need to worry about since Apache 
will reject anything that is not a valid HTTP request anyway. Perhaps 
you should be more concerned with requests that *are* valid HTTP but 
that could cause buffer overruns and such.
