Progressive Web App–Redirect from HTTP to HTTPS

I’m currently working on a Progressive Web App(PWA) using ASP.NET Core. After creating our initial setup I used the Google Lighthouse chrome extension to check my application.

The results looked OK, I only had one failed audit: “Does not redirect HTTP traffic to HTTPS”.

Let’s fix this by adding the AspNetCore Rewrite middleware:

	using Microsoft.AspNetCore.Rewrite;
	var options = new RewriteOptions()
	.AddRedirectToHttps();
	app.UseRewriter(options);

If you need to specify a port, you can add some extra parameters:

	var options = new RewriteOptions()
	.AddRedirectToHttps(statusCode:301, sslPort: 44373);
	app.UseRewriter(options);
