If you have a Windows hosting plan and you wish to redirect it from http to https, create a web.config file and add the following command:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<clear />
<rule name="Redirect all requests to https" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action
type="Redirect" url="https://{HTTP_HOST}{ REQUEST_URI}"
redirectType="Permanent" appendQueryString="false" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
Save it and upload it to your root folder.
Note: If there’s already a web.config file on the server, open it with an editor, add the above command and save it.
