Ajuda com Htaccess

[LuanMartinsTI 0]

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>

e me desculpem se está no local errado, vi html e pensei é o mais perto de XML
