Thanks for joining our newsletter. Need to move your existing website to a new domain or TLD? Go ahead and try it! Prepend www. For example: I own www. How Redirects Work But this is only one step in the lookup process. When you enter a website into your browser, what happens? Your browser checks to see if it has a cached version of the website.
The resolver asks the root nameservers for the DNS information. The authoritative nameserver answers with the IP address in the DNS record for that domain and subdomain, if appropriate. The other nameservers and servers pass back the information to the browser. The browser connects to the IP address specified in the DNS record, which is the web server for that website. What happens here is a sort of handshake. In Chrome, the browser will alert the user that the website is not secure.
A lot of SysAdmins run into this kind of issue, and there are a few reasons why. User and web server exchange certificate information and keys to create a secure connection. AKA: the handshake. Permanent Redirect Exactly what it says.
This is the standard for most redirects. Temporary Redirect Tells search engines that you may change it later, so they should check again. Hard link You can also configure a hidden frame redirect to not include the path the user entered into their browser. The authoritative server, in turn, can respond with any address it prefers. In particular, it can respond with the address of the service replica that it finds best for the query. The answer will finally be returned to the client which will contact the replica instead of the service machine see Figure 2.
As long as the client uses DNS names to reference the service, and not network addresses, this scheme will give the effect of client redirection. DNS-based redirection has several advantages. The most visible one is that it achieves transparency without losing scalability. It is transparent because the clients are obliged to use the addresses provided by the authoritative DNS server, and cannot establish whether these addresses belong to the home machine of the service or to any of its replicas.
DNS as a distributed name resolution service proved to be very efficient, even though the amount of people using it has increased tremendously with the growth of the Internet. Another vital advantage of using DNS to redirect clients is that it is a natural way of informing the clients about the service addresses. It is used by many existing network services, and is very likely to be used by those to come as well.
Moreover, DNS is supported by a huge infrastructure of millions of DNS servers, capable of caching the answers our redirector generates. Once we make this infrastructure work for us, both efficiency and availability of our redirector considerably increase. One more important advantage of DNS is that it allows multiple replica addresses to be returned, enabling the client to choose one from them.
This feature was not supported by any of the previously discussed redirection mechanisms. The last advantage of DNS-based redirection is its good maintainability. Deployment of the complete redirection mechanism boils down to launching a single modified DNS server, and subsequently delegating a service domain to this server.

Doing things all by yourself isn't much fun. Invite your colleagues to manage the redirects and work as a team. Connect your software to automatically create redirects via our API.
Import and export redirects at any point in the process; whatever works for you. How long does the DNS change take? You've changed the DNS at your domain registrar, but redirect.
