HTTPS www redirects in web.config

Question

I have the following in my web.config to force https;

<rule name="Redirect to https" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
</rule>

But I want to force the www. as well so that all of these would go to the https://www version. What I need to achieve:

http://www.domain.tld/whatever
http://(no-www)domain.tld/whatever
https://(no-www)domain.tld/whatever

Thank you.

Answer 1

This rule will do the following:

• Redirect to HTTPS
• Force www

<rule name="Redirect to https" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAny">
<add input="{HTTPS}" pattern="off" />
<add input="{HTTP_HOST}" pattern="^www." negate="true" />
</conditions>
<action type="Redirect" url="https://www.example.com{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
</rule>

All that you need is to change www.example.com with your domain name
