HSTS: Fix automatic re-routing of http:// to https:// on localhost in Web Browsers



If you're doing local Web develop with multiple development tools you've probably run into a problem where you end up not being able to access a local site via unsecured `http://` requests and automatically get redirected to `https://` no matter what you try. If you don't have a certificate set up for the site you may not even be able to access the site at all. Turns out this usually is due to HSTS which is a nasty little bugger of a security protocol that is applied universally to a domain even in applications that don't use HSTS. In this post I discuss how HSTS works and why it can be a problem for local development as well as how to clear out the HSTS cache or avoid using it locally.
