I’ve tried every single example I could find, they all produce an internal server error. I have these rules set up (this works, no error):

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}/index.php !-f
RewriteRule ^((/?[^/]+)+)/?$ ?q=$1 [L]

So if it’s not an existing file or an existing directory with an index.php we redirect. For instance, http://domain.com/foo/bar becomes http://domain.com/?q=foo/bar

Thing is, I want the trailing slash stripped. So take off the /? at the end of the rule. How do I make it so that http://domain.com/foo/bar/ becomes http://domain.com/foo/bar with a visible redirect first (fixing the client’s URL), and only then the real, silent redirection to ?q=?

Everywhere I look I see this:

RewriteRule (.*)/$ $1 [R,L]

But it gives me a 500 error if I insert it before my rule.

    If foo/bar exists as a real directory, then the server will be redirecting the client to foo/bar/ (with the trailing slash). It has to do that in order for relative URLs to work correctly on the client. If you put in a rule to rewrite that back to foo/bar with a redirect then there will be a loop. An easy way to test if that’s happening is to specify a path that doesn’t exist at all (I assume from your index.php detection that the directory tree actually exists). The nonexistent path won’t trigger the built-in redirect.

    If I setup a similar set of rules to yours (plus the suggested slash-removal rule) I can see the difference between a directory that exists and one that doesn’t. The ones that don’t work as expected, the ones that do cause Firefox to say This page isn’t redirecting properly. IE8 says something similar. Perhaps the Apache setup you’re using can detect it and turns it into the 500 error?
