Redirect to SSL using IIS7 UrlRewrite

I am using IIS7's new UrlRewrite engine (http://learn.iis.net/page.aspx/460/using-url-rewrite-module/). I want to redirect certain pages to an SSL page, and keep other pages off SSL for unneccessary encryption processing.

So far I have the redirect to SSL rule started, but it is not working. I am trying to keep a list of secure pages in the rewritemaps for easy maintenance and adding more secure pages in the future. Does anyone see why this is not working?

<rules>
	<rule name="RequiresSSL-Redirect" stopProcessing="true">
		<match url="(.+)" />
		<conditions>
			<add input="{HTTPS}" pattern="off" />
			<add input="{RequiresSSL:{R:1}}" pattern="(.+)" />
		</conditions>
		<action type="Redirect" url="https://{HTTP_HOST}/{C:1}" appendQueryString="true" redirectType="Permanent" />
	</rule>
</rules>
<rewriteMaps>
	<rewriteMap name="RequiresSSL">
		<add key="path/to/secure/page.aspx" value="path/to/secure/page.aspx" />
		<add key="nextpath/to/secure/page.aspx" value="nextpath/to/secure/page.aspx" />
	</rewriteMap>
</rewriteMaps>
