URL Rewrite for hosted mvc.net site.

Recently I've been working on deployment of an MVC.NET based site to Azure. As a part of this I needed to re-map request url's from the Azure dns host name to my dns host. After a few fumbling starts I opted to use the IIS URL Rewriter module. The module is installed (by default) on Azure so it was good to go. I spent a good while looking into some of the other available options, in particular the SEO templates for lower-case and trailing-slash. I've had prior experience with url re-writing modules... not much of it good. I did manage to get a re-write rule set to trim and lower case my urls, but I felt it was too fragile to keep.
In the end I settled on just a host-name redirect.

<system.webServer>
<.other.>
<rewrite>
  <rules>
    <rule name="HostName" enabled="true" stopProcessing="false">
    <match url="(.*)" />
    <conditions>
      <add input="{HTTP_HOST}" pattern="YOUR\.SERVICENAME\.cloudapp\.net" />
    </conditions>
    <action type="Redirect" url="{MapSSL:{HTTPS}}/YOURHOSTNAME/{R:1}"/>
    </rule>
  </rules>
  <rewriteMaps>
  <rewriteMap name="MapSSL" defaultValue="OFF">
    <add key="ON" value="https://" />
    <add key="OFF" value="http://" />
  </rewriteMap>
  </rewriteMaps>
  </rewrite>
</system.webServer>
