Fala galera blz, então estou com um problema para converter um arquivo htaccess para web.config, não é muito minha are, eu queria transformar o seguinte codigo htaccess

RewriteEngine On

RewriteRule ^upload$ upload_photo.php [NC,END]
RewriteRule ^index$ index.php [NC,END]
RewriteRule ^teste$ teste2.php [NC,END]
RewriteRule ^public/preview/([0-9]+)-([0-9]+).png public/preview/$1-$2.png [NC,END]
RewriteRule ^public/purchased/([0-9]+)-([0-9]+).png fetch_photo.php?userId=$1&photoId=$2&tmb=0 [NC,END]
RewriteRule ^public/purchased/([0-9]+)-([0-9]+)_small.png fetch_photo.php?userId=$1&photoId=$2&tmb=1 [NC,END]
RewriteRule ^crossdomain.xml$ crossdomain.xml [NC,END]

Else

RewriteRule ^(.*)$ - [R=404]

em um web config, eu fiz da seguinte forma, mas não funcionou

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 <system.webServer>
 <rewrite>
 <rules>
 <rule name="rule 1N" stopProcessing="true">
 <match url="^upload$" ignoreCase="true" />
 <action type="Rewrite" url="/upload_photo.php" appendQueryString="true" />
 </rule>
 <rule name="rule 2N" stopProcessing="true">
 <match url="^preview/([0-9]+)-([0-9]+).png" ignoreCase="true" />
 <action type="Rewrite" url="/public/preview/{R:1}-{R:2}.png" />
 </rule>
 <rule name="rule 3N" stopProcessing="true">
 <match url="^purchased/([0-9]+)-([0-9]+).png" ignoreCase="true" />
 <action type="Rewrite" url="/fetch_photo.php?userId={R:1}&amp;photoId={R:2}&amp;tmb=0" />
 </rule>
 <rule name="rule 4N" stopProcessing="true">
 <match url="^purchased/([0-9]+)-([0-9]+)_small.png" ignoreCase="true" />
 <action type="Rewrite" url="/fetch_photo.php?userId={R:1}&amp;photoId={R:2}&amp;tmb=1" />
 </rule>
 <rule name="rule 5N" stopProcessing="true">
 <match url="^crossdomain.xml$" ignoreCase="true" />
 <action type="Rewrite" url="/crossdomain.xml" />
 </rule>
 <rule name="rule 6N">
 <match url="^(.*)$" />
 <action type="CustomResponse" statusCode="404" subStatusCode="404" statusReason="Not Found" />
 </rule>
 </rules>
 </rewrite>
 </system.webServer>
</configuration>
