Question

http://domain.de to https://domain

Answer 1

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>

Answer 2

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)

<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>

Answer 3

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 4

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 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>
