re-write rule for a REST API (php)

Hi, 

I need some help on how to write the web config so that a url will go via a php script.

On apache i had some lines of code in a .htaccess file which looked like this:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* api.php/$0 [L]

Which works a treat if i go to :

localhost/api/scripts/

or 

localhost/api/scripts/{name}

it works fine, but the deployment server it turns out isnt apache, its IIS so i need to work out how to get the web config to do the same sort of thing that the .htaccess did.

So i tried (with vane) to get it to work this is what i have come up with so far:

<?xml version="1.0" encoding="UTF-8"?><configuration><system.webServer><rewrite><rules><rule name="redirect to api" stopProcessing="true"><match url="/scripts/" /><action type="Rewrite" url="api.php" /></rule></rules></rewrite></system.webServer></configuration>

The idea is i have this file sat in the folder webroot/api/ also in there i have my api.php along with other php files for it to work. so the aim is that the user can put in:

webroot/api/scripts/

or

webroot/api/scripts/scriptname

and the api.php captures the uri and then handles it.

but it doesnt work,

if anyone has any ideas that would be fantastic
