Proxy server

A proxy server acts as an intermediary between devices (such as computers or smartphones) and other servers on the internet. If you use a proxy server, when your visitors make a request for a resource (such as a web page or a file), the proxy server forwards that request to the destination server on behalf of the visitor. The server then sends the response back to the proxy server, which, in turn, sends it back to the visitor. Proxy servers can provide anonymity and privacy as they hide the visitor’s IP address from the server; they can also be used to filter content, cache resources locally, and much more. To learn more about proxy servers, refer to What Is a Proxy Server Used For? (And How Does It Work?).

SPF record

An SPF (Sender Policy Framework) record is a type of DNS (Domain Name System) record that helps prevent email spoofing and phishing by specifying which mail servers are authorized to send emails on behalf of a domain. SPF is an email authentication method that allows domain owners to declare a list of authorized mail servers permitted to send emails using their domain name. SPF is one of several email authentication methods, and it works alongside DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to enhance email security and prevent email-related abuse. For more information about SPF records, refer to What Is an SPF Record? A Complete Guide.


Secure Sockets Layer (SSL) is a standard security technology used to establish an encrypted link between a web server and a browser that ensures all data transferred between the web server and browser remains private and secure. SSL certificates are issued by trusted Certificate Authorities (CAs) and are installed on web servers. When a web browser connects to a site secured with SSL, it checks the SSL certificate to verify the website’s identity and establish a secure connection. Once the connection is established, data transmitted between the server and browser is encrypted and cannot be intercepted or read by unauthorized parties. At Kinsta all verified domains are automatically protected by our Cloudflare integration, which includes free SSL certificates. To learn more about SSL, refer to How SSL Works and Why It’s Important.

Static website

A static website is a type of website that is comprised of fixed, pre-built files. These websites are typically written in HTML and may include CSS for styling and JavaScript for additional functionality, but the content doesn’t change dynamically based on user interactions or other factors. Static websites are generally faster to load because there is no need for server-side processing or database queries. The content is served directly to the user without additional processing. For more information about static websites and the difference between static and dynamic sites, refer to What Is a Static Website? The Absolute Beginner’s Guide. At Kinsta, you can host static sites for free; refer to Static Site Hosting for more information.


A taxonomy is a way of organizing and classifying content in WordPress. It allows you to group and categorize content types to make it easier for your readers to find related content. There are 2 main taxonomies:

  • Categories: These can be used to create a hierarchical structure with parent and child categories, such as a parent category called “accessories” with child categories “hats” and “gloves”. You can assign more than one category to a post.
  • Tags: Tags don’t have a hierarchical structure. Each tag is independent and can be used for specific keywords or topics. You can assign multiple tags to posts.

You can also create custom taxonomies for specific organizational needs. To learn more, refer to What is a Taxonomy? WordPress Taxonomies Explained.


Top Level Domain (TLD) is the last part of a domain name, for example, .com, .net, .org, or .io. They link your domain name to web servers and are an essential part of the Domain Name System (DNS), the hierarchical naming system used to identify and locate resources on the internet. To find out more about TLD, refer to What Is a TLD? Top-Level Domains ExplainedTo help you choose the right domain extension for your site, refer to What Are Domain Extensions? (And How to Choose a Domain Extension).


Transport Layer Security (TLS) is a more recent version of SSL. It ensures privacy and data integrity between a web browser and a website by encrypting the data transmitted between them. It provides security features such as authentication, encryption, and data integrity verification, helping to protect sensitive information from eavesdropping, tampering, and forgery. Similar to SSL, TLS uses digital certificates to verify the authenticity of websites and establish secure connections. TLS certificates are issued by trusted Certificate Authorities (CAs) and contain information about the identity of the website and the cryptographic keys used for encryption. Kinsta includes free SSL certificates with TLS 1.2 and TLS 1.3  already enabled, both of which are secure and supported by all major browsers. For more information about the difference between SSL and TLS, refer to TLS vs SSL: What’s the Difference? Which One Should You Use?


A trackback is used to notify another website that you have linked to one of its posts. It is a way for websites to communicate when one site references or links to content on another. Trackbacks are a form of acknowledgment and provide a means for content creators to see who links to their posts. Trackbacks and pingbacks are similar in purpose but differ in how they communicate. Trackbacks use HTTP POST requests, while pingbacks use a standardized XML-RPC protocol. Trackbacks can be susceptible to spam, and website administrators may need to use anti-spam measures to filter out unwanted or irrelevant trackback notifications; due to this, many websites choose to disable trackbacks and opt to use other communication methods, such as pingbacks or social media sharing. To learn more, refer to What Is a Trackback?


Time to Live (TTL) is a time limit for how long your computer remembers where a website is located. It is a setting on the DNS that determines the duration the website data is available on a network before the router clears it. When the TTL expires, the router needs to retrieve the information again to ensure you have the latest information from the website. TTL is also used on Content Delivery Networks (CDNs) to cache data on the servers; this determines how long the CDN servers retain data for your website before retrieving updated information. To learn more about TTL, including how to choose and change your TTL, refer to What Is TTL (And How Do You Choose the Right One)?


TypeScript is an open-source programming language developed and maintained by Microsoft. It is a superset of JavaScript, meaning any valid JavaScript code is also valid TypeScript code.
