Redirect to HTTPS results in Infinite LOOP

I'm trying to redirect all visitors in a sub directory to the HTTPS version, but when I use the code below, I get an endless loop.

I'm running IIS7.5 and I put this code into the web.config file in the root of my subdirectory.

What might be causing the infinite loop?

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

I don't know the correct syntax to fix it, but doesn't that rule apply to all URLs? You want it only to apply to http: and never https.

Here ya go

<rule name="Redirect to HTTPS" stopProcessing="true">
      <match url="(.*)" ignoreCase="true" />
      <conditions logicalGrouping="MatchAll">
            <add input="{HTTPS}" pattern="off" ignoreCase="true" />
      </conditions>
      <action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" />
</rule>

dgrafx - What does redirectType = "Found" do?

Seems I should use redirectType="Permanent" any thoughts?

The code below was found to work and not cause the infinite loop. Not sure why it works while the code I initially showed causes the loop:

<rewrite>
<rules>
<rule name="HTTP to HTTPs" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent"/>
</rule>
</rules>
</rewrite>
