Using the following code in your web.config file automatically redirects visitors to the HTTPS version of your site:
-------------
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="HTTP to HTTPS redirect" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
--------------
If you have an existing web.config file:
- Ensure you have sections (i.e. opening and closing tags) for:
- system.webServer (which contains rewrite)
- rewrite (which contains rules)
- rules (which contains one or more rule sections)
- Insert any of those sections that do not exist.
- Insert the entire rule section, including match, conditions, and action, inside the rules section.
