Reverse Proxy On IIS

Question

I have a asp.net website hosted on iis 7.5. I am trying to use iis rewriter module for reverse proxy. I have implemented the following code in web.config file. The code is working for 1 website news.mysite.co.uk but not working for blog.mysite.co.uk. It's looks like i have not implemented outbond rule correctly.

      <rule name="Route the requests for newa" stopProcessing="true">
        <match url="^news/(.*)" />
        <conditions>
          <add input="{CACHE_URL}" pattern="^(https?)://" />
        </conditions>
        <action type="Rewrite" url="{C:1}://news.mysite.co.uk/{R:1}" />
        <serverVariables>
          <set name="HTTP_ACCEPT_ENCODING" value="" />
        </serverVariables>
      </rule>
      <rule name="Route the requests for blog" stopProcessing="true">
        <match url="^blog/(.*)" />
        <conditions>
          <add input="{CACHE_URL}" pattern="^(https?)://" />
        </conditions>
        <action type="Rewrite" url="{C:1}://blog.mysite.co.uk/{R:1}" />
        <serverVariables>
          <set name="HTTP_ACCEPT_ENCODING" value="" />
        </serverVariables>
      </rule>
    </rules>
    <outboundRules>
      <rule name="Add application prefix 2" preCondition="ResponseIsHtml2">
        <match filterByTags="A, Area, Base, Form, Frame, Head, IFrame, Img, Input, Link, Script" pattern="^/(.*)" />
        <conditions>
          <add input="{URL}" pattern="^/.*" />
        </conditions>
        <action type="Rewrite" value="/blog/{R:1}" />
      </rule>
      <rule name="ReverseProxyOutboundRule2" preCondition="ResponseIsHtml2">
        <match filterByTags="A, Area, Base, Form, Frame, Head, IFrame, Img, Input, Link, Script" pattern="^http(s)?://blog.mysite.co.uk/(.*)" />
        <action type="Rewrite" value="/blog/{R:2}" />
      </rule>

      <rule name="Add application prefix" preCondition="ResponseIsHtml1">

Answer 1

Here is the final working code.

<rewrite>
<rules>
  <rule name="ReverseProxyInboundRule1" stopProcessing="true">
    <match url="^news/(.*)" />
    <action type="Rewrite" url="http://news.mysite.co.uk/{R:1}" />
    <serverVariables>
      <set name="HTTP_ACCEPT_ENCODING" value="" />
    </serverVariables>
  </rule>
  <rule name="ReverseProxyInboundRule2" stopProcessing="true">
    <match url="^blog/(.*)" />
    <action type="Rewrite" url="http://blog.mysite.co.uk/{R:1}" />
    <serverVariables>
      <set name="HTTP_ACCEPT_ENCODING" value="" />
    </serverVariables>
  </rule>
</rules>
<outboundRules>
  <rule name="ReverseProxyOutboundRule1" preCondition="ResponseIsHtml2">
    <match filterByTags="A, Img" pattern="^/(.*)" />
    <conditions>
      <add input="{URL}" pattern="^/(news|blog)/.*" />
    </conditions>
    <action type="Rewrite" value="/{C:1}/{R:1}" />
  </rule>
  <rule name="ReverseProxyOutboundRule2" preCondition="ResponseIsHtml2">
    <match filterByTags="A, Form, Img" pattern="^http(s)?://news.mysite.co.uk/(.*)" />
    <action type="Rewrite" value="/news/{R:2}" />
  </rule>
  <rule name="ReverseProxyOutboundRule4" preCondition="ResponseIsHtml2">
    <match filterByTags="A, Form, Img" pattern="^http(s)?://blog.mysite.co.uk/(.*)" />
    <action type="Rewrite" value="/blog/{R:2}" />
  </rule>
  <preConditions>
    <preCondition name="ResponseIsHtml2">
      <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
    </preCondition>
  </preConditions>
</outboundRules>
</rewrite>
