IIS rewrite does not work

Hi,

I have a URL which I need to rewrite only at one particluar value. URL looks like - http://***************languageCode=da&countryCode=DA&ver=v11&productType=anonymous&isInBusinessHour=true&portal_id=1000&acname=prod

What I need is that when anyone comes to this URL, it should be rewritten to ***************languageCode=da&countryCode=DA&ver=v11&productType=anonymous&isInBusinessHour=true&portal_id=444400000001000&acname=prod

etc.,

<rewrite>
            <rules>
  <rule name="444400000001000" patternSyntax="ExactMatch">
                    <match url="(.*)" />
                    <conditions>
                        <add input="{QUERY_STRING}" pattern="^(.*)portal_id=1000(.*)$" />
                    </conditions>
                    <action type="Rewrite" url="{R:1}?{C:1}portal_id=444400000001000{C:2}" appendQueryString="false" logRewrittenUrl="true" />
                </rule>
  <rule name="444400000001001">
                    <match url="(.*)" />
                    <conditions>
                        <add input="{QUERY_STRING}" pattern="^(.*)portal_id=1001(.*)$" />
                    </conditions>
                    <action type="Rewrite" url="{R:1}?{C:1}portal_id=444400000001001{C:2}" appendQueryString="false" />
                </rule>

But it does not seems to work

Any thoughts?

Thank you,

Veeren
