Multiple http bindings to HTTPS - iis

Question

Windows Server 2012
I have 1 IIS container with 4 different URLs for one domain and 2 domains in total as below (set with the bindings)
www.site1.com
site1.com
www.site1.co.uk
site1.co.uk
www.site2.com
site2.com
www.site2.co.uk
site2.co.uk
www.site1.com - is the primary domain, meaning any combination of the URLs above must take the user to www.site1.com or www.site2.com
I have the below rule which takes these sites to the primary URL
<rule name="PrimarySite" patternSyntax="Wildcard" stopProcessing="true">
<match url="*" />
<conditions logicalGrouping="MatchAny">
<add input="{HTTP_HOST}" pattern="site1.co.uk" />
<add input="{HTTP_HOST}" pattern="www.site1.co.uk" />
<add input="{HTTP_HOST}" pattern="site1.com" />
</conditions>
<action type="Redirect" url="http://www.site1.com/{R:0}" />
</rule>
I now would like the same but for HTTPs so added a new rule (just for site 1 but i would do the same for site 2).
<rule name="site1HTTPS" stopProcessing="true">
<match url="(.*)" />
<conditions trackAllCaptures="true" logicalGrouping="MatchAny">
<add input="{HTTP_HOST}" pattern="site1.co.uk" />
<add input="{HTTP_HOST}" pattern="www.site1.co.uk" />
<add input="{HTTP_HOST}" pattern="site1.com" />
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://{C:1}{REQUEST_URI}" appendQueryString="false" redirectType="Permanent"/>
</rule>
When i add this i receive a redirecting loop error and have tried different combinations but it just doesnt seem to work.
What have i missed off (I have to rules in total)?

Answer 1

Use MatchAny for 3 {HTTP_HOST} and {HTTPS} will mess up the redirection logic.
You can combine 3 conditions into one so that {HTTP_HOST} and {HTTPS} can be used with "MatchAll" side by side.
<rule name="test">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="(site1|site2)\.(com|co.uk)" />
<add input="{HTTPS}" pattern="^off$" />
</conditions>
<action type="Rewrite" url="https://{HTTP_HOST}{REQUEST_URI}" />
