Sharepoint - Redirect HTTP to HTTPS

There are some online-tipps which recommend the use of the IIS Rewrite module. I do not prefer this way.

My preferred way is done with SharePoint AAMs and IIS-Bindings:

  • Alternate Access Mappings: Configure your HTTPS URL in Default-Zone. Add an additional "Internal URL" and map it to the "Default" Zone. Should look like this: AAM
  • Add both the HTTP and the HTTPS binding to your IIS-Website: IIS-Bindings

This configuration will redirect your users from HTTP to HTTPS even if they call a subsite of SharePoint.
