From my experiences, I'd suggest that you go with with the
proxy/reverse-proxy/SiteAccess configuration unless you want to do
SSL.

Look into the SiteAccess package.  I think it'll do most of what you
want.

Try :

RewriteRule ^/cgi-bin/.* - [L]

Essentially, this says do nothing and don't rewrite the url further.
I don't think that the passthrough is necessary if you aren't really
rewriting anything.  I've used this with aliased directories, but not
with script-aliased directories, so it may not work.  Another thing,
check your <DIRECTORY "/usr/.../cgi-bin/">...</DIRECTORY> directive to
make sure its proper.
