A small note on the subject:
mod_rewrite modifies the mapping of an url to the filesystem to a lot wider

Not sure whether you have full control over Apache or just only are twisting
it via .htaccess. Unfortunately the two have slightly different syntax and
behaviour... Assuming you are using a .htaccess at the root of the site.

Be more selective, example given only do html by:
RewriteEngine on
RewriteRule (.*\.html)$ cgi-bin/test [NC,L]

Note the NC for no(t) case-sensitive matching.

You might consider testing presence of static content before giving dynamic
response:
RewriteEngine on
RewriteCond %{ REQUEST_FILENAME} !-f
RewriteRule (.*\.html)$ cgi-bin/test [NC,L]
(Might be handy for error documents ... )

Running .htaccess based rewrites has a performance penalty.
To minimize the effect, consider setting up folders like
\images
\scripts
\test
The latter will hold hardly no files, but at least a .htaccess reading like
RewriteEngine on
RewriteBase /
RewriteCond %{ REQUEST_FILENAME} !-f
RewriteRule (.*\.html)$ cgi-bin/test [NC,L]

It does work, but the way you want it ;-)
It only matches a path like /a_B/bC/C_d, but NOT /a_B/bC/C_d.html.
Notice all dynamic urls MUST BE exactly 2 levels below the site's root.
