I am trying to rewrite a html response with an outboundrule, but it is not working: This are my inbound and outbound rules:

<rules>             
    <rule name="IE56 Do not gzip js and css" stopProcessing="false">
            <match url="\.(css|js|emz|jpg|htm|html)" />
            <action type="None" />
            <serverVariables>
             <set name="HTTP_ACCEPT_ENCODING" value="" />
               </serverVariables>
    </rule>


<rule name="Route the requests for eserver" patternSyntax="ECMAScript">
    <match url="^eServer/(.*)" />
    <conditions logicalGrouping="MatchAny">
               <add input="{CACHE_URL}" pattern="^(https?)://" />
    </conditions>
    <action type="Rewrite" url="{C:1}://mckyesvr/eServer/{R:1}" />
    <serverVariables>
               <set name="HTTP_ACCEPT_ENCODING" value="" />
    </serverVariables>
    </rule>

      <outboundRules>               
    <rule name="ReverseProxyOutboundRule1" preCondition="ResponseIsHtml1">
     <match filterByTags="A, Area, Base, Form, Frame, Head, IFrame,Img,    Input, Link, Script" pattern="^http(s)?://mckyesvr/eServer/(.*)" ignoreCase="true" />
        <conditions>
                       <add input="{URL}" pattern="/PageLoader" negate="true" />
        </conditions>
        <action type="Rewrite" value="/eServer/{R:2}" />
</rule>


<rule name="ReverseProxyOutboundRule8" preCondition="ResponseIsHtml1">
<match pattern="http://mckyesvr/eServer/PageLoader.asp?Page=Process_Safety.dsp"/>
<action type="Rewrite" value="/eServer/PageLoader.asp?Page=Process_Safety.dsp" />
</rule>

They work perfectly with almost every HTML response except with the ones that have this HTML reponses form:

"<html xmlns:v="urn:schemas-microsoft-com:vml"
    xmlns:o="urn:schemas-microsoft-com:office:office"
    xmlns:x="urn:schemas-microsoft-com:office:excel"
    xmlns="http://www.w3.org/TR/REC-html40">

.......etc and this is the part that I want to rewrite: <_a href="http://mckyesvr/eServer/PageLoader.asp?Page=Process_Safety.dsp" target="_parent">Go Back to Process Safety------

I have tried changing the compressing, change the outbound rules, move a thousand parameters but nothing has worked out until now, I don't know why this is happening just with an HTML response as the one indicated above, it looks like it is coded because Outboundrules don't catch it.
