Redirect 301 with Webconfig

Question

I use a rule that works more does not seem correct. I think it ends up giving two redirect 301.

            <!--Forçar https-->
            <rule name="Https" stopProcessing="true">
              <match url="^" ignoreCase="false" />
              <conditions>
                <add input="{HTTP_X_FORWARDED_PROTO}" pattern="https" ignoreCase="false" negate="true" />
                <add input="{HTTPS}" pattern="off" ignoreCase="false" />
              </conditions>
              <action type="Redirect" redirectType="Permanent" url="https://{HTTP_HOST}{URL}" />
            </rule>
            <!--Forçar Www-->
            <rule name="Www" stopProcessing="true">
                  <match url="^(.*)" ignoreCase="false" />
                  <conditions>
                    <add input="{HTTP_HOST}" pattern="^(site\.com\.br)(:80)?" />
                  </conditions>
                  <action type="Redirect" redirectType="Permanent" url="https://www.site.com.br/{R:1}" />
            </rule>

The first is to force https and the second force www. How to assemble a single rule that does both. It has to be on the web.config itself.
