URL Rewrite update protocol and domain if URL is http:// - url

Question

I would like to redirect all calls to http://www.domain.com/csp/ to https://secure.doman.com/csp/ using URL rewrite running on IIS 8.5. I would like the URL on the browser to update accordingly. I cannot get it to work.
Below is the section of the web.config file with the rule
<rules>
<rule name="CSP to SSL" enabled="true" stopProcessing="true">
<match url="^http://www.domain.com/csp/(.*)$" />
<conditions>
<add input="{CACHE_URL}" pattern="^http://" />
</conditions>
<action type="Redirect" url="https://secure.domain.com/csp/{R:1}" />
</rule>
</rules>
Thank you.

Thanks to peterviola's reply at http://forums.iis.net/t/1214515.aspx?Change+to+https+and+adjust+domain+if+URL+uses+http+and+matches+a+particular+path I managed to get to the solution I was seeking.
<rule name="csp2HTTPS" enabled="true" stopProcessing="true">
<match url="(.*)csp/(.*$)" ignoreCase="true" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" appendQueryString="true" redirectType="Permanent" />
</rule>
<rule name="csp2subdomain" enabled="true" stopProcessing="true">
<match url="(.*)csp/(.*$)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_HOST}" pattern="^(www.|)domain.com$" />
</conditions>
<action type="Redirect" url="https://secure.domain.com{REQUEST_URI}" appendQueryString="true" redirectType="Permanent" />
</rule>
The above solution works. I can't understand why this could not be done using one rule.
Hope this helps.
