Nghttp2
nghttp2 is a C library. It is an implementation of HTTP/2. History nghttp2 was created by Tatsuhiro Tsujikawa as a derivative of spdylay, an implementation of SPDY, a communications protocol created by Google in 2009, in C. Several well-known projects use nghttp2 to implement HTTP/2, including Apache and cURL. Features HTTP/2 implementation nghttp2 will send a WINDOW_UPDATE frame upon consuming more than half of the flow control window. For instance, if the sender specifies the SETTINGS_INITIAL_WINDOW_SIZE as 65,535 octets in the SETTINGS frame, nghttp2 will send a WINDOW_UPDATE frame upon exceeding 32,768 octets. The initial window size may be changed using the -w and -W flags. Tools nghttp2 offers multiple tools. nghttp is a command-line tool that uses nghttp2 to output HTTP/2 messages from a URL. nghttp's dependency-based priority is based on Firefox; when a connection is established, nghttp sends five PRIORITY frames. Other tools provided include nghttpd, an HTTP/2 se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTTP/2
HTTP/2 (originally named HTTP/2.0) is a major revision of the HTTP network protocol used by the World Wide Web. It was derived from the earlier experimental SPDY protocol, originally developed by Google. HTTP/2 was developed by the HTTP Working Group (also called httpbis, where "" means "twice") of the Internet Engineering Task Force (IETF). HTTP/2 is the first new version of HTTP since HTTP/1.1, which was standardized in in 1997. The Working Group presented HTTP/2 to the Internet Engineering Steering Group (IESG) for consideration as a Proposed Standard in December 2014, and IESG approved it to publish as Proposed Standard on February 17, 2015 (and was updated in February 2020 in regard to TLS 1.3 and again in June 2022). The initial HTTP/2 specification was published as on May 14, 2015. The standardization effort was supported by Chrome, Opera, Firefox, Internet Explorer 11, Safari, Amazon Silk, and Edge browsers. Most major browsers had added HTTP/2 support by the end of 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

CURL
cURL (pronounced like "curl", ) is a free and open source computer program for transferring data to and from Internet servers. It can download a URL from a web server over HTTP, and supports a variety of other network protocols, URI schemes, multiple versions of HTTP, and proxying. The project consists of both a library (libcurl) and command-line tool (curl), which have been widely ported to different computing platforms. It was created by Daniel Stenberg, who is still the lead developer of the project. History The software was first released in 1996, originally named ''httpget'' and then became ''urlget'', before adopting the current name of curl. The name stands for "Client for URL". The original author and lead developer is the Swedish developer Daniel Stenberg, who created curl to power part of an IRC bot, because he wanted to automatically provide currency exchange rates, fetched from a website, to users in an IRC chat room.

QUIC
QUIC () is a general-purpose transport layer network protocol initially designed by Jim Roskind at Google. It was first implemented and deployed in 2012 and was publicly announced in 2013 as experimentation broadened. It was also described at an IETF meeting. The Chrome web browser, Microsoft Edge, Firefox, and Safari all support it. In Chrome, QUIC is used by more than half of all connections to Google's servers. QUIC improves performance of connection-oriented web applications that before QUIC used Transmission Control Protocol (TCP). It does this by establishing a number of multiplexed connections between two endpoints using User Datagram Protocol (UDP), and is designed to obsolete TCP at the transport layer for many applications. Although its name was initially proposed as an acronym for ''Quick UDP Internet Connections'', in IETF's use of the word, QUIC is not an acronym; it is simply the name of the protocol. QUIC works hand-in-hand with HTTP/3's multiplexed connections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTTP/3
HTTP/3 is the third major version of the Hypertext Transfer Protocol used to exchange information on the World Wide Web, complementing the widely deployed HTTP/1.1 and HTTP/2. Unlike previous versions which relied on the well-established TCP (published in 1974), HTTP/3 uses QUIC (officially introduced in 2021), a multiplexed transport protocol built on UDP. HTTP/3 uses similar semantics compared to earlier revisions of the protocol, including the same request methods, status codes, and message fields, but encodes them and maintains session state differently. However, partially due to the protocol's adoption of QUIC, HTTP/3 has lower latency and loads more quickly in real-world usage when compared with previous versions: in some cases over four times as fast than with HTTP/1.1 (which, for many websites, is the only HTTP version deployed). As of September 2024, HTTP/3 is supported by more than 95% of major web browsers in use and 34% of the top 10 million websites. It has ...

Load Testing
Load testing is the process of putting demand on a structure or system and measuring its response. Software load testing Physical load testing Many types of machinery, engines, structures, and motors are load tested. The load may be at a designated safe working load (SWL), full load, or at an aggravated level of load. The governing contract, technical specification or test method contains the details of conducting the test. The purpose of a mechanical load test is to verify that all the component parts of a structure including materials, base-fixings are fit for task and loading it is designed for. Several types of load testing are employed * Static testing is when a designated constant load is applied for a specified time. * Dynamic testing is when a variable or moving load is applied. * Cyclical testing consists of repeated loading and unloading for specified cycles, durations and conditions. The ''Supply of Machinery (Safety) Regulation 1992 UK'' state that load testi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
