web.config Index Redirect - asp.net

Question

I use a standard web.config file for my projects that are hosted on Windows servers. It takes care of 2 tasks.
It redirects the non-www version of the site to the www version.
It redirects the index file to the root.
See below:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<rewrite>
<rules>
<rule name="CanonicalHostNameRule1" stopProcessing="true">
<match url="index\.asp(?:l)?" />
<conditions>
<add input="{HTTP_HOST}" pattern="example\.com$" />
</conditions>
<action type="Redirect" url="http://www.example.com/" />
</rule>
<rule name="CanonicalHostNameRule2" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^example\.com$" />
</conditions>
<action type="Redirect" url="http://www.example.com/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
This works great, except for 1 problem. The index redirect is redirecting all sub-directories to the main, index.
For example:
http://www.example.com/index.asp is redirecting to http://www.example.com like it should.
But, http://www.example.com/about/index.asp is also redirecting to http://www.example.com. I would like it to redirect to http://www.example.com/about/
Any help would be greatly appreciated.

Well, after getting no response here, I posted on various .Net forums and finally got an answer. This rule will fix it:
<rule name="redirect index.asp" stopProcessing="true">
<match url="^(\w*/)?index\.asp" />
<conditions>
<add input="{HTTP_HOST}" pattern="domain\.com$" />
</conditions>
<action type="Redirect" url="http://www.domain.com/{R:1}" />
</rule>
