URL rewrite with IIS 7

Hello,

I am using ARR/Proxy setup with IIS. By Using Rewrite, i am able to redirect traffic from external urlhttp://comanyEXTurl to internal url http://companyINTurl

The problem is that we have some files (jpgs, pdfs) on external server which are hard coded to some other sites. with rewrite being in place, those links are broken as server rediretd everything to intenal URL.

My web config looks like this:

<?xml version="1.0" encoding="UTF-8"?><configuration><system.webServer><rewrite><rules><clear /><rule name="ReverseProxyInboundRule1" stopProcessing="true"><match url="(.*)" /><conditions logicalGrouping="MatchAll" trackAllCaptures="false"></conditions><action type="Rewrite" url="http://10.10.10.10/{R:1}" /></rule></rules></rewrite></system.webServer></configuration>

example of jpg/pdf location is: http://http://comanyEXTurl/fldr1/fldr2/abc.jpg

sorry for my ignorance but i am new to this...
