Redirect HTTP to HTTPS on Windows IIS — Forced HTTPS

In my previous blog, I have SSL Certificate related setting done and IIS running with both HTTP and HTTPS. There are times where we want to make sure all traffics are using HTTPS, so we must redirect HTTP traffics to HTTPS.

In order to do so, we need to:

  1. Install rewrite module on IIS
  2. Configure HTTP to HTTPS rules
  3. That’s it and verify!

Let’s get started

Install rewrite modules from Microsoft’s website.

In order to forced HTTPS, we need to configure rewrite rules, start by clicking on URL Rewrite feature.

You can add rewrite rule on IIS Server or Web sites. If you configure on IIS Server, it means all Web sites under it will be affect where rule is only affected to particular Web site if you configure it on Web site level.

In my blog, I will configure on IIS Manager level.

Next, click Add Rule(s), follow by Blank rule, then OK below.
