Hi,
mod_security is interesting, it definitely looks like the right idea for
this guy's situation, but it is kind of funny in a way, if you need
mod_security you are already somewhat screwed, but it is nice to have
around.. :)

Ouch. Very old apache version with very vulnerable php apps. Youseem to
be in a very bad situation.
Anyway, the mod_alias directives cannot act on the query string (thepart
after the ?). If you need that, you can do something like
RewriteEngine OnRewriteCond %{QUERY_STRING} go\.phpRewriteRule .* - [F]
You can also look at mod_security (external module).
