HTTP/2 allows the server to "push" content, that is, to respond with data for more queries than the client requested. This allows the server to supply data it knows a web browser will need to render a web page, without waiting for the browser to examine the first response, and without the overhead of an additional request cycle.

Version history for TLS/SSL support in web browsers tracks the implementation of Transport Layer Security protocol versions in major web browsers.
As a DNS provider, Dyn provides to end-users the service of mapping an Internet domain name—when, for instance, entered into a web browser—to its corresponding IP address. The distributed denial-of-service (DDoS) attack was accomplished through numerous DNS lookup requests from tens of millions of IP addresses. [6]
A tag cloud (a typical Web 2.0 phenomenon in itself) presenting Web 2.0 themes. Web 2.0 (also known as participative (or participatory) [1] web and social web) [2] refers to websites that emphasize user-generated content, ease of use, participatory culture, and interoperability (i.e., compatibility with other products, systems, and devices) for end users.
Heartbleed is a security bug in some outdated versions of the OpenSSL cryptography library, which is a widely used implementation of the Transport Layer Security (TLS) protocol.
On 7 June 2021, LiteSpeed Web Server (and OpenLiteSpeed) 6.0.2 was released and became the first version to enable HTTP/3 by default. [34] Caddy web server v2.6.0 (released 20 September 2022) has HTTP/3 enabled by default. [35] Nginx supports HTTP/3 since 1.25.0 (released 23 May 2023).
DNS is robust by design against failure and requires that a lack of response is met by inquiries to other DNS servers. [ 83 ] Andrew Lee, CEO of ESET North America, objected that since the bill would require internet service providers to filter DNS queries for the sites, this would undermine the integrity of the Domain Name System.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
