Forcing IIS to rewrite all requests to HTTPS

I often need to ensure that an IIS web site uses HTTPS instead of HTTP. The easiest way to do this is with a URL rewriting rule. The rule I use is below.

<rule name="Redirect to HTTPS" stopProcessing="true">
    <match url="(.*)" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
        <add input="{HTTPS}" pattern="^OFF$" />
    </conditions>
    <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
</rule>

This will redirect any request that is not “HTTPS” to an “HTTPS” address.
