Outbound rules not performed/succeeded

Hi all,

I'm trying to rewrite some urls but for an unknow reason I can't get some rules to work.

I used the 'Url Rewrite' module inside IIS 7.5 (Win 2K8R2):

      <outboundRules>
        <rule name="replace .aspx by .html (for non-default aspx)" preCondition="ASPX/html" enabled="true">
          <match pattern="^(.*/)(Pages/)(?!Default)([^\/]*)(\.aspx)$" />
          <action type="Rewrite" value="{R:1}{R:3}.html" />
        </rule>
        <rule name="Replace pages/default.aspx" preCondition="ASPX/html" enabled="true">
          <match pattern="([^\s\.]*?)/Pages/Default.aspx" />
          <action type="Rewrite" value="{R:1}/" />
        </rule>
                <rule name="aspx to html" preCondition="ASPX/html" enabled="true">
                    <match filterByTags="None" pattern="^(.*)\.aspx$" />
                    <action type="Rewrite" value="{R:1}.html" />
                </rule>
        <preConditions>
          <preCondition name="ASPX/html">
            <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
          </preCondition>
        </preConditions>
      </outboundRules>

1. I tried to convert every aspx pages to html Under FailedReqLogFiles, I've seen that this rules had EvaluationPerformed=0 and EvaluationSucceedee=0

2. I tried to replace the '\Pages\Default.aspx' to '\' and It worked (EvaluationPerformed=32 and EvaluationSucceedee=32)

3. I tried to replace the NOT '\Pages\Default.aspx' to '.html' and It didn't work (EvaluationPerformed=0 and EvaluationSucceedee=0)

I really don't understand why only one rule is working. I tried to evaluate my RegEx and my tests were correct...

Have you got any idea of the problem? Thanks
