![]() Your browser asks the resolver (usually your ISP) if they have the DNS information for the domain. It realizes it doesn’t, so it starts a DNS query.Your browser checks to see if it has a cached version of the website.When you enter a website into your browser, what happens? To better understand how HTTP redirects work, we need to go back to the very beginning. How Do Redirects Workīut this is only one step in the lookup process. The web server will respond with a 301 redirect and the destination URL. When you create an HTTP redirection record, you’re actually making an A record that points to that web server. That’s because they require the help of a dedicated web server to store all of the redirects. HTTP redirects operate very differently from traditional DNS records. Okay, but what if I own and I want to redirect it to ? I would have to use an HTTP redirect since the second hostname is not one in my current zone. So how are regular DNS records like A and CNAME different from HTTP redirects?ĭNS records are confined to redirects within the same FQDN (Fully Qualified Domain Name) or zone. You can also test for redirects to HTTPS by prepending to a URL. Go ahead and try it! Prepend > - > 301 Moved Permanently > - Status: 301 Moved Permanently Code: 301 Server: nginx/1.10.3 (Ubuntu) Date: Thu, 17:56:53 GMT Content-Type: text/html Content-Length: 194 Connection: close Location: How about when to go to the “naked” version of your domain, like. Instead, they are records that point one hostname or IP to another. There are other kinds of “redirects” at the DNS level, but they don’t operate over HTTP or HTTPS protocols. You can also do it at the DNS level using an HTTP redirection record (we’ll talk more about this in a minute). Like in the previous example, you can set up a redirect on your web server to automatically send all traffic to the HTTPS version of the site, no matter what page they are visiting. Keep in mind that for a lot of the examples in this article, there is more than one way to create the redirect. ![]() Recently, browsers like Google Chrome are showing “nonsecure” badges for websites still running over HTTP. Since HTTPS is now a standard for all websites, it’s become more important than ever to redirect traffic to the HTTPS version of a website. The 301 simply tells users that is the intended destination for our website. In this case, we want our users to only visit the HTTPS version of our website. Redirects are commonly used to tell website visitors and search engines which URL is the one you want them to see. > - > 301 Moved Permanently > - Status: 301 Moved Permanently Code: 301 Server: nginx/1.10.3 (Ubuntu) Date: Wed, 22:11:33 GMT Content-Type: text/html Content-Length: 194 Connection: close Location: Redirects that you CAN do with DNS, as well as an introduction to HTTP/HTTPS redirections.Ī redirect is an HTTP response with a 301 status code and the new location. If you don't have access to your web server, you will need to contact your web hosting provider. This is something you have to configure on your web server (because it manages the protocol). No, you cannot redirect HTTP to HTTPS at the DNS level. If you have ever considered setting up your redirects at the DNS level… this article will answer every question you could ever have. Are you migrating from HTTP to HTTPS and keeps breaking?.Need to move your existing website to a new domain or TLD?.
