php - Apache vhost rewrite goes wrong with existing folders -

i want vhost rewrite urls such as:
http://dev.example.com/cool/story/bro

to:
http://dev.example.com/index.php?url=cool/story/bro

unless specifying existing file such as:
http://dev.example.com/images/duck.png

---

it works fine when have url uses existing folder such as:
http://dev.example.com/images

it strangely redirects to:
http://dev.example.com/images/?url=images

when should rewrite to:
http://dev.example.com/index.php?url=images

---

here's current code:

<virtualhost *:80>         servername dev.example.com         documentroot /var/www/dev/public          php_flag display_errors 1         php_value error_reporting 30719          <directory "/var/www/dev/public">                 rewritebase /                 rewriteengine on                 rewritecond %{request_filename} !-f                 rewriterule ^(.*)$ index.php?url=$1 [l]         </directory> </virtualhost> 

i've been trying fix hours can't see problem, hope can help.

you'll want specify rewritecond paths existing directories in addition ones existing files.

rewritebase / rewriteengine on rewritecond %{request_filename} !-f [or] rewritecond %{request_filename} -d rewriterule ^(.*)$ index.php?url=$1 [l]
