Reverse Proxy

Hi There,

I'm currently trying to point my blog folder on my site to another host. I do not want to host WordPress on my IIS server. Ok, so I have thewww.domain.com/blog/ working it pulls through the blog. But when I go towww.doamin.com/blog/ijasifiad/ or a post it just gives me a 404.

I have already rewritten the URLS in the wordpress blog so i do not need any outbound rules? 

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<urlCompression doStaticCompression="false" doDynamicCompression="false" />
<rewrite>
<rules>
<rule name="Routeforrequestfishnews" stopProcessing="true">
<match url="^blog/(.*)" />
<conditions>
<add input="{CACHE_URL}" pattern="^(https?)://" />
</conditions>
<serverVariables>
<set name="HTTP_ACCEPT_ENCODING" value="1" />
</serverVariables>
<action type="Rewrite" url="http://myblog.com/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
