Answer 1

RewriteRule ^test/(.*)$ /test/index.php?req_dir=$1 [L,QSA]

but this depends on other rules in the .htaccess file, so in your case it might not work without changing other rules.

Explanation of the rule: (.*) matches everything after test/ and is captured into the rewriting variable $1.

If you want a 302 redirect (ie the server tells the browser to use a different file instead), use [L,R,QSA] instead. Usually a rewrite is better than a redirect, because a redirect shows the rewritten url in the address bar. If you worry about canonical pages (a SEO technique), a 302 redirect to the canonical page is better than a direct rewrite.
