.htaccess mod_alias and mod_rewrite redirects are ignored

Question

I want to redirect all requests to my index.php script in such a way that everything that goes after http://mysite/ would passed to index.php as url-argument. For example, http://mysite/moo.css should become http://mysite/index.php/moo.css and http://moosite/moo/foo/bar/ should become http://index.php/moosite/moo/foo/bar/.

Easy, huh?

But not RedirectMatch (.*) index.php/$1, nor RewriteRule ^(.*)$ index.php/$1 [R,L] (or others regexp like that; RewriteEngine on was not ommitted; mod_rewrite and mod_alias are turned on) took effect.

What's going on?

Answer 1

Without knowing anything more, my guess would be that the Allowoverride directive is missing for that directory. (Captain obvious style answer, but still easy to overlook).
