    # If the file or directory exists, show it
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^(.+) - [PT,L]
    
    # Blank queries get sent to the index
    RewriteRule ^$ index.php [L]
    
    # All other queries get sent to the index as index.php/whatever
    RewriteRule ^(.*)$ index.php/$1 [L]
    
    RewriteCond $1 !^(index\.php|images|robots\.txt|js|css|user_guide|/awstats)
