Windows Server Web.config Strip Index Filename - asp.net

Question

I am using the following web.config file to redirect the non-www version of a site to the www version. However, I would also like to have it strip the file name of the index file as well.
For example:
redirecting www.example.com/index.html to www.example.com
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<rewrite>
<rules>
<rule name="CanonicalHostNameRule" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^www\.example\.com$" negate="true" />
</conditions>
<action type="Redirect" url="http://www.example.com/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
Edit:
Here is my updated config file. But, its causing a 500 error, now.
See CodingGorilla's answer below :)

Answer 1

In order to get rid of the index.html after the redirect, drop the {R:1}. But then you will need to modify that rule so that it triggers only for /index.html requests and create a new rule that triggers on other pages that includes the {R:1} so that requests for example.com/mypage.html will still get redirected properly.

And the final answer is!
Based on our chat conversation, I think this is the final rule set:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<rewrite>
<rules>
<rule name="CanonicalHostNameRule1" stopProcessing="true">
<match url="index\.htm(?: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>
