If you want to redirect www to non www:

  1. Add DNS entry for www.yourdomain.com to refer to your server's public IP
  2. Then you need to Edit Bindings of your website and "Add Binding" www.yourdomain.com
  3. 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>

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.

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>

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>

Redirecting https://www.example.com to https://example.com I had to do 2 steps

  1. 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}

  2. 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

Solution 6:[6]

These rewrite rules matches the following URL's:

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)

<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="HTTPS" enabled="true" patternSyntax="Wildcard" stopProcessing="true">
                    <match url="*" />
                    <conditions>
                        <add input="{HTTPS}" pattern="off" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" />
                </rule>
                <rule name="WWW" stopProcessing="true">
                    <match url="^(.*)$" />
                    <conditions>
                        <add input="{HTTP_HOST}" pattern="^(www\.)(.*)$" />
                    </conditions>
                    <action type="Redirect" url="https://example.com{PATH_INFO}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
