Trying to create tiny urls, getting redirect loop

I'm trying to create tiny urls like this:

site.com/abc123

goes to:

site.com/index.php?token=abc123

but I keep getting redirect loops no matter what I try, or it tries to redirect to index.php?token=开发者_如何学Pythonindex.php..

Current .htaccess is:

Options +FollowSymLinks
Options -MultiViews
RewriteEngine On
RewriteRule ^([^/]*)$ /index.php?token=$1 [L]

Here's what I've done (I'm redirecting alphanumeric codes like http://myurl.com/b32ad ):

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule (.*) /index.php?token=$1 [L]

I have answered a similar question yesterday: htaccess: Redirect a Dynamic URL - Show only Static URL - Double Content

This should do it:

RewriteCond %{QUERY_STRING} ^token=([a-zA-Z0-9]+)$
RewriteRule ^/ /%1? [R=302,L]

That's strange since you have the [L] option attached to that rule. Could there be an external redirect caused by something else?

Anyway, you could limit the rule to requests for non-existing files (maybe directories, too).

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)$ /index.php?token=$1 [L]
