重定向问题“未指定输入文件”

Question

I'm working on a url shortner script. It's located at http://mini.ample.se/ and the short URL will look something like http://mini.ample.se/[abc..]

my .httaccess file looks like this

<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteOptions MaxRedirects=1
   RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteCond %{REQUEST_FILENAME} !-l
   RewriteRule ^([a-zA-Z0-9_-]+)$ redirect.php?alias=$1 [L]
</IfModule>

when I try it out with ex. mini.ample.se/a I get "No input file specified" error. I know it got something to do with the redirecting and not finding my redirect.php file but I'm not sure what.

redirect.php file looks like this

$alias = trim(mysql_real_escape_string($_GET['alias']));

if (!preg_match("/^[a-zA-Z0-9_-]+$/", $alias)) {
  header("Location: ".SITE_URL, true, 301);
  exit();
}

if (($url = get_url($alias))) {
    header("Location: $url", true, 301);
    exit();
}

header("Location: ".SITE_URL, true, 301);

Thanks!

I'm pretty sure this is a 'file not found' issue, that the php file is not found and its kicking back an error, I think your rewrite needs to have a condition that will not 'rewite' a certain request:

RewriteCond $1 !^(redirect\.php)

$1 being the value of course that is being passed.. just an example but I believe this is whats happening. Give it a try.
