TLS sendfile is a feature implemented in some web servers that allows a web server to send encrypted data directly from a file to the client without first loading it into the server's memory. This can improve server performance because less memory is required and the web server can handle...

TLS Record Direct is a technology implemented in some web servers like LiteSpeed or OpenLiteSpeed that makes it possible to transfer SSL/TLS-encrypted content faster by reducing the overhead for TLS record processing.Usually, SSL/TLS encryption is performed at the application layer (layer...

IPv4 and IPv6 are versions of the Internet Protocol (IP) used to transmit data on the Internet. The main difference between IPv4 and IPv6 is the number of IP addresses available.IPv4 uses 32-bit addresses and can therefore provide a maximum of 4.3 billion unique addresses. However, given...

Concurrent connections refers to the number of simultaneous connections between a client and a server. There is a limit to the number of simultaneous connections a server can handle before it slows down or even crashes. This limit is determined by factors such as available bandwidth, server...

"Apply changes with zero downtime" means making updates or modifications to a system or application without causing any interruptions or downtime for users or customers. In other words, the system remains available and operational throughout the entire update process, with no disruption of...

"Recovers from service failures instantly" means that the server software is designed to automatically recover from any failures or crashes that may occur, without any manual intervention. This ensures that the service remains available and responsive to users even in the event of unexpected...

Video streaming is the process of delivering video content over the internet in real-time or near real-time. It allows users to watch videos on their devices without having to download them first. In video streaming, the video data is transmitted in small packets over the internet and displayed...

SPDY (pronounced: speedy) was a network protocol developed by Google to improve the speed of website loading. It was first published in 2009 and introduced as an experiment. The protocol was later refined and released in 2012 as SPDY 3.1.SPDY was developed to reduce webpage loading times by...

A WebSocket proxy is a server that acts as an intermediary between WebSocket clients and WebSocket servers. WebSocket is a protocol that enables bi-directional communication between a client and a server. A WebSocket proxy can be used to optimize the connection between the client and the server,...

Asynchronous I/O (Input/Output) is a concept in computer science that allows I/O operations to be performed asynchronously and without waiting. Unlike synchronous I/O processing, where the application blocks while waiting for an I/O operation, asynchronous I/O processing performs I/O operations...
