What are HTTP status codes?

Imagine, after a long time, you need to open a bookmark that you have more than a few years already. You try to open it, and…suddenly you see an error – “404 Page not found”. The page you were looking for has gone without a trace, maybe the whole website is missing, or maybe it was just a small change of the URL, but you will probably never know.

This is your first touch with an HTTP status codes, and specifically with 400-type. There are different status code types: 1?? Information responses, 2?? Success, 3?? Redirection, 4?? client errors and 5?? server errors. In the context of redirection, we focus on the 3?? status codes – 301 and 302 Redirects.

301 moved permanently

A 301 redirect is a permanent redirect that informs search engines and browsers that the requested page has been permanently moved to a new location. It ensures that both users and search engines are directed to the new URL and all the existing traffic, link juice, and SEO value of the old page are transferred to the new one.

This redirection is very convenient if you have changed to a new domain. You can redirect to the new one using the 301 redirection and Google will start indexing the new page (the page where the 301 redirects). The search engine will understand that object is moved from address A to address B permanently, and it will start “forgetting” the old one.

You can configure 301 redirects in different ways – using HTML, PHP, scripts, .htaccess (for Apache) or web.config (for IIS).

This process is a bit more time consuming, and you need specialized knowledge.

If you don’t have programming skills, and you don’t have a full-time programmer at your disposal, you can take advantage of our free feature called Web Redirects.

When to use a 301 Redirect

• Permanent URL Changes: If you have permanently moved or renamed a page on your website, implementing a 301 redirect is crucial. It ensures that users who try to access the old URL are automatically redirected to the new URL, preserving their experience and preventing broken links.
• Consolidating Content: When you merge two or more pages into one, a 301 redirect can be used to redirect users and search engines from the old URLs to the new consolidated URL. This consolidation helps avoid duplicate content issues and improves SEO by consolidating link equity.
• Domain Migrations: If you are changing your domain name, a 301 redirect can be used to redirect all traffic from the old domain to the corresponding pages on the new domain. This redirect ensures a smooth transition and helps maintain your search engine rankings.

Is there a limit to using 301 Redirects?

When it comes to using 301 redirects, it’s important to understand their impact on your site’s performance and SEO. Technically, you can use numerous 301 redirects, but it’s best to avoid creating long chains where one URL redirects to another and so forth. These redirect chains can slow down your site, confusing both users and search engines. Each redirect introduces a slight delay as the server processes the request, and multiple redirects can accumulate significant delays, leading to slower page load times and potentially frustrating visitors.

Search engines like Google may not pass the full SEO value through a series of redirects. The more redirects in a chain, the less SEO benefit the final URL might receive. Therefore, it’s best to keep your redirects as direct as possible. Ideally, a redirect should point straight to the final destination without any intermediate steps. This helps preserve SEO value and ensures faster load times, providing a better user experience.

Managing a large number of redirects can also become cumbersome. Regularly reviewing and updating your redirects is crucial to ensure they remain necessary and efficient. Removing outdated redirects helps keep your site clean and streamlined.

302 moved temporarily

302 Redirect is easier to use, it can be done with a simple JavaScript, but it has small applications. The most common use is in e-commerce websites. It is used for products that are temporarily out of stock. When your client opens the page of the product, instead of seeing the sad 404 error, he/she can be redirected to a different product or category. It might help you keep the client and leave a good impression.

So, 302 is commonly used when a website is undergoing maintenance or when a page is temporarily inaccessible. Unlike the 301 redirect, a 302 redirect does not transfer the SEO value and traffic from the old page to the new one.  It won’t replace the new page with the previous, and in the long-term, it can damage your PageRank and consequently can lower the visits to the page.

When to use a 302 Redirect

• Temporary Page Changes: If a page on your website is temporarily unavailable, such as during maintenance or updates, a 302 redirect can be used to redirect users to a temporary page or a maintenance notice. It signals to search engines that the change is temporary, and the original page will return.
• A/B Testing: When conducting A/B testing or running multiple versions of a page simultaneously, a 302 redirect can be used to send a portion of the traffic to one version and another portion to a different version. This allows you to compare the performance of different page variations without affecting the search engine rankings.

3 Best practices for implementing redirects

1. Redirect Chains: Avoid creating long chains of redirects as it can slow down page load times and confuse search engines. Whenever possible, aim to have a direct redirect from the old URL to the new one.
2. Correct HTTP Status Codes: Ensure that you set the appropriate HTTP status code (301 or 302) in the redirect response. This ensures search engines and browsers interpret the redirect correctly.
3. Update Internal Links: After implementing redirects, update internal links throughout your website to point to the new URLs. This helps maintain a consistent user experience and ensures search engines can crawl and index the new pages correctly.

How to configure redirects 301 and 302? Step by step guide

1. First you need to determine the type of redirect you need – 301 or 302 redirects

2. Then you need to access your website’s configuration files or Content Management System (CMS). The process may vary depending on your platform or hosting provider. Here are some common methods:

• Apache web server (.htaccess file): If you’re using Apache, you can add redirect rules in the .htaccess file located in your website’s root directory.
• Nginx web server (nginx.conf file): For Nginx, you need to edit the nginx.conf configuration file, which is typically found in the /etc/nginx/ directory.
• Content Management Systems: If you’re using a CMS like WordPress, Joomla, or Drupal, you can usually configure redirects using built-in plugins or modules.

3. Write the redirect rules:

• For a 301 Permanent Redirect, the rule typically looks like this in Apache’s .htaccess file:

And for Nginx’s nginx.conf file:

• For a 302 Temporary Redirect, the rule is similar but with a different status code:

For Nginx:

4. Save the configuration changes and restart your web server if necessary. This step ensures that the changes take effect.

5. Test the redirects: Open a web browser and try accessing the old URL. It should automatically redirect you to the new URL based on the status code you specified.

Remember to replace “/old-page.html” with the actual URL or path you want to redirect from, and “https://www.example.com/new-page.html” with the destination URL or path you want to redirect to.

Web Redirect Record

Web redirect record is an essential tool in Domain Name System (DNS) management that guides all site visitors to a specific URL when visiting a particular domain, subdomain, or a specific path. This feature enhances overall website navigation and supplies an impressive, dynamic online user experience. It’s vital in performing URL forwarding, controlling domain aliases, and creating a seamless flow when a domain name or a webpage is altered or deleted.

Moreover, web redirect record plays a vital role in ensuring an effective and encrypted connection through the Secure Sockets Layer (SSL). SSL protects an internet connection and safeguards any sensitive data that’s being transferred between two systems. It prevents cybercriminals from reading and modifying any information transferred, including personal and credit card details. At ClouDNS, we offer this service for no additional cost. Our Free SSL Certificates are available in our Premium DNS, DDoS protected DNS, and GeoDNS plans.

Combining web redirect records with SSL can give an extra layer of safety by redirecting users to the HTTPS version of your website. This indicates that your website has an SSL certificate and the data transmitted between the users and the website is encrypted and secure.

But remember, implementing web redirects and SSL seamlessly requires efficient SSL certificate monitoring and web monitoring. Web (HTTP/HTTPS) monitoring check involves overseeing your website’s performance and availability to ensure a quality user experience. It detects potential issues in real time. This enables businesses to act immediately to resolve any potential problems.

Our Web Redirect Record (WR) is now an exclusive feature of our enhanced DNS plans, ensuring your redirect needs are seamlessly managed.

You just need to access the control panel and redirect from your old domain to a new one.

You can do it in just a few minutes – follow the instructions of our video, and you’ll be ready in no time.

Using our control panel, you can easily do both redirection methods – 301 or 302.

Now that you know them, you can use them accordingly and keep your SEO in order and your users happy.

But first, let’s explain a little bit more about what DNS records actually are.

DNS records briefly explained

DNS records are simple text-based instructions for a specific domain name. Their main purpose is to set precise rules for the domain. Additionally, they are created and gathered in a zone file in the DNS zone. All that information is stored on the Authoritative DNS server for the particular domain name. As we mentioned, DNS records are completely made of text. Therefore, they are pretty light. That allows DNS administrators to edit and adjust them easily. 

Every DNS record type has a different function, so each of them is important for the proper management of the domain name. Moreover, when a user makes a request, the Recursive DNS servers search for a precise DNS record type. 

For the rest of this article, we are going to present to you some of the most important and interesting DNS record types. 

Common DNS record types

There are several types of DNS records, each serving a different purpose. Let’s take a look at some of the most common ones:

SOA Record

SOA (Start of Authority) shows the start of the authority DNS zone and specifies the global parameters of the zone. Every zone must have one, and you can’t add two per zone. It has the following parameters: Serial number, Primary Nameserver, DNS admin’s email, Refresh Rate, Retry Rate, Expire Time and TTL.

A and AAAA Records

These DNS record types are perhaps the most popular and also most important. The A record and the AAAA record are both responsible for mapping a domain name to its corresponding IP address. This is what enables users to access your website via its domain name. The difference is that A record points to an IPv4 and the AAAA record to IPv6.

MX Record

The MX record, commonly also known as mail exchange record, is used to specify the email server responsible for accepting incoming email messages for a domain name. This DNS record type is crucial for ensuring that your email gets delivered to the correct mail server. Basically, it says which server should receive the incoming emails. If it is not directed well, you won’t receive emails.

CNAME Record

CNAME record is another very popular DNS record type where the short acronym “CNAME” stands for Canonical Name. It allows you to point one hostname to another, not to an IP address like the A and AAAA records. You can use it when you want to create an alias for a domain name. It serves just for subdomains. It is important to note that you can add only one CNAME record per hostname.

TXT Record

The TXT record allows you to add and store text-based information about a domain name. There are all kinds of TXT records and some of them people can easily understand, and others are specifically for machines to read. For example, DKIM (DomainKeys Identified Mail) record is a TXT record that associates a domain name with a specific email message. There is also DMARC (Domain-based Message Authentication, Reporting, and Conformance) record that identifies and blocks spam and phishing emails by verifying the emails.

SPF Record

Creating an SPF (Sender Policy Framework) record shows who is authorized to send emails with a particular domain. Without it, all the emails you send will go directly to the spam folder of the recipients. It is helpful for preventing email spoofing and phishing attacks.

NS Record

The short acronym “NS” stands for Nameservers, and this NS record points the domain name to its authoritative DNS servers responsible for the DNS zone. The NS record is essential for ensuring that your domain name is properly registered and configured.

SRV Record

SRV records are responsible for defining the locations of servers for specified services, such as voice-over IP (VoIP), instant messaging, and others.

Web Redirect (WR) Record

The Web Redirect record does precisely what it says. It redirects from one address to another. There are a few types: 301 redirect which is a permanent redirect, and 302 redirect, which is temporary, if the address has been moved but not permanently. You can do such a redirection with SSL too.

ALIAS Record

ALIAS record is a very similar to the CNAME record. It allows you to add various hostnames for the same subdomain. You can use it for the root domain as well. This type of record is built into the ClouDNS.

RP Record

The RP record, or Responsible person record, shows who is responsible for the domain name and specifies its email address.

SSHFP Record

Secure Shell Fingerprint record is used for Secure Shell (SSH). The SSHFP record is typically used with DNSSEC enabled domains. When an SSH client connects to a server, he or she checks the corresponding SSHFP record. If there is a match, the server is legit, and it is safe to connect to it.

PTR Record

The PTR record, also commonly known as the Pointer record, points an IP address (IPv4 or IPv6) to a domain name. It is the exact opposite of the A and AAAA records, which match the hostnames to IP addresses. PTR records are used for Reverse DNS.

NAPTR Record

IP telephony uses Naming Authority Pointer records, or for short NAPTR records,  for mapping the servers and the users’ addresses in the Session Initiation Protocol (SIP).

CAA record

Certification Authority Authorization (CAA record) record gives the ability to the DNS domain name holder to issue certificates for his/her domain. The record can set policies for the whole domain or for specific hostnames.

Wildcard DNS Record

The Wildcard DNS record will match requests for non-existing domain names. It is specified with a “*” for example *.cloudns.net

How many DNS record types are there?

The Domain Name System (DNS) offers an extensive collection of DNS record types, each tailored to specific functions within the internet’s architecture. Currently, there are over 60 standardized DNS record types, which highlights the system’s complexity and adaptability to various networking needs.

Among these record types are the fundamental A and AAAA records, which respectively map domain names to IPv4 and IPv6 addresses, enabling the routing of internet traffic. MX records handle mail server information, directing emails to the appropriate destination, while CNAME records help aliasing one domain name to another.

Beyond these basics, there is a large number of specialized DNS record types designed to cater to specific requirements. TXT records store text data, serving purposes like domain verification and SPF (Sender Policy Framework) for email authentication. PTR records enable reverse DNS lookups, aiding in network diagnostics and security measures.

Moreover, DNSSEC (Domain Name System Security Extensions) has introduced additional record types which strengthen DNS security. These include DNSKEY records for cryptographic keys and RRSIG records for digital signatures, ensuring the authenticity and integrity of DNS data.

As technology advances, new record types may emerge to address challenges and requirements in internet communication and security. Despite this evolution, the core DNS record types remain vital components of the internet’s infrastructure, supporting its functionality and reliability.
