Answer 1

I think this will work for you, the search pattern has the optional www and redirects using the back reference C:2, the rule has a condition to only run against non https.
This is the pattern:
"^(www\.)?(.*)$"
where:
{C:0} - www.domain.de
{C:1} - www.
{C:2} - domain.de
Here's the rule in full:
<rewrite>
<rules>
<rule name="SecureRedirect" stopProcessing="true">
<match url="^(.*)$" />
<conditions>
<add input="{HTTPS}" pattern="off" />
<add input="{HTTP_HOST}" pattern="^(www\.)?(.*)$" />
</conditions>
<action type="Redirect" url="https://{C:2}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>

Answer 2

The accepted answer doesn't handle the special case https://www.domain.de.
These rules do the complete job:
<rewrite>
<rules>
<rule name="Redirect to HTTPS without www" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{HTTPS}" pattern="^OFF$" />
<add input="{HTTP_HOST}" pattern="^(www\.)?(.*)$" />
</conditions>
<action type="Redirect" url="https://{C:2}/{R:1}" redirectType="Permanent" />
</rule>
<rule name="Special case for HTTPS with www" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{HTTPS}" pattern="^ON$" />
<add input="{HTTP_HOST}" pattern="^(www\.)(.*)$" />
</conditions>
<action type="Redirect" url="https://{C:2}/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>

If you want to redirect www to non www:
Add DNS entry for www.yourdomain.com to refer to your server's public IP
Then you need to Edit Bindings of your website and "Add Binding" www.yourdomain.com
Add a rewrite rule to your website using iis:
<rule name="Remove WWW" patternSyntax="Wildcard" stopProcessing="true">
<match url="*" />
<conditions>
<add input="{CACHE_URL}" pattern="*://www.*" />
</conditions>
<action type="Redirect" url="{C:1}://{C:2}" redirectType="Permanent" />
</rule>

Answer 4

If you want something more flexible than for your three examples, change your HTTP_HOST pattern to : \w+\.\w+$. That would work for all three examples plus anything else, like subdomain.abcdef.domain.de.
If you use this regex either encase it in parenthesis or change C:1 to C:0 in your action.

Answer 5

This is what worked for me:
<rule name="NameRule1" stopProcessing="true" enabled="true" >
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^example\.com$" negate="true" />
</conditions>
<action type="Redirect" url="http://example.com/{R:1}" />
</rule>

Answer 6

Redirecting https://www.example.com to https://example.com I had to do 2 steps
Select the website, click "URL Rewrite" -> Click "Add Rule" -> Choose "Cononcial domain name" -> select your domain (without the www) -> make sure rule is at the top -> highlight the rule and click "Edit" -> and update "Redirect URL" at the end of the rule to include the 's' - https://example.com/{R:1}
I had to also create a new website with the domain www.example.com, new app pool and select the SSL cert and point it to a folder containing the following (for some reason StackOverflow wont display the code I pasted below for the rewrite rule but just google IIS rewrite rule)
After doing both steps only then does it work as desired

Answer 7

Tried many of solutions but below works for me:
Right click on Domain and Add a Site bindings, add one more domain with www:
2. Restart services. it should work.

Answer 8

These rewrite rules matches the following URL's:
www.example.com
http://www.example.com
https://www.example.com
They will all redirect to: https://example.com
These rewrite rules may redirect twice because of the separate rules. (I'm a newbie with regex)
