Cross-Origin Resource Sharing
Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served. A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos. Certain "cross-domain" requests, notably Ajax requests, are forbidden by default by the same-origin security policy. CORS defines a way in which a browser and server can interact to determine whether it is safe to allow the cross-origin request. It allows for more freedom and functionality than purely same-origin requests, but is more secure than simply allowing all cross-origin requests. The specification for CORS is included as part of the WHATWG's Fetch Living Standard. This specification describes how CORS is currently implemented in browsers. An earlier specification was published as a W3C Recommendation. Technical overview For Ajax and HTTP request methods that can modify data (usuall ...

Blink (layout Engine)
Blink is a browser engine developed as part of the Chromium project with contributions from Google, Meta, Microsoft, Opera Software, Adobe, Intel, IBM, Samsung, and others. It was first announced in April 2013. Naming Blink's naming was influenced by the non-standard presentational blink HTML element, which was introduced by Netscape Navigator and supported by Presto- and Gecko-based browsers until August 2013. Blink has, contrary to its name, never functionally supported the element. History Blink is a fork of the WebCore component of WebKit, which was originally a fork of the KHTML and KJS libraries from KDE. It is used in Chrome starting at version 28, Microsoft Edge starting at version 79, Opera (15+), Vivaldi, Brave, Amazon Silk and other Chromium-based browsers and frameworks. Much of WebCore's code was used for features that Google Chrome implemented differently such as sandboxing and the multi-process model. These parts were altered for the Blink fork ...

Microsoft Edge
Microsoft Edge is a proprietary, cross-platform web browser created by Microsoft. It was first released in 2015 as part of Windows 10 and Xbox One and later ported to other platforms as a fork of Google's Chromium open-source project: Android and iOS, macOS, older Windows versions (Windows 7 and later), and most recently Linux. It was created as the successor to Internet Explorer (IE). Edge was initially built with Microsoft's own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. In late 2018, it was announced that Edge would be completely rebuilt as a Chromium-based browser with Blink and V8 engines. The new Edge was publicly released in January 2020, and on Xbox platforms in 2021. Microsoft has since terminated security support for the original browser (now referred to as Microsoft Edge Legacy), and in Windows 11 it is the default web browser (for compatibility with Google Chrome). In May 2022, according to StatCounter, Microsoft Edge became the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebKit
WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as on the iOS and iPadOS version of any web browser. WebKit is also used by the BlackBerry Browser, PlayStation consoles beginning from the PS3, the Tizen mobile operating systems, a browser included with the Amazon Kindle e-book reader, and on Nintendo consoles beginning from the 3DS Internet Browser and onward. WebKit's C++ application programming interface (API) provides a set of classes to display Web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited. WebKit started as a fork of the KHTML and KJS libraries from KDE, and has since been further developed by KDE contributors, Apple, Google, Nokia, Bitstream, BlackBerry, Sony, Igalia, and others. WebKit supports macOS, Windows, Linux, and various other Unix-like operating systems. On April 3, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opera Mini
Opera Mini is a mobile web browser made by Opera. It was primarily designed for the Java ME platform, as a low-end sibling for Opera Mobile, but it is now developed exclusively for Android. It was previously developed for iOS, Windows 10 Mobile, Windows Phone 8.1, BlackBerry, Symbian, and Bada. As of 2022, the Android build is the only version still under active development. Opera Mini was derived from the Opera web browser. Opera Mini requests web pages through Opera Software's compression proxy server. The compression server processes and compresses requested web pages before sending them to the mobile phone. The compression ratio is 90% and the transfer speed is increased by two to three times as a result. The pre-processing increases compatibility with web pages not designed for mobile phones. However, interactive sites which depend upon the device processing JavaScript do not work properly. In July 2012, Opera Software reported that Opera Mini had 168.8 million users as o ...

Opera Mobile
Opera Mobile is a mobile web browser for smartphones, tablets and PDAs developed by Opera. History The first devices to run a mobile edition of Opera were the Psion Series 5, Psion Series 5mx, Psion Series 7, and then Psion netBook. They ran Opera Mobile 3.6, released in 2000. Opera Mobile was ported to the Windows Mobile operating system in 2003. * Version 6.0 was the initial release. * On June 25, 2003, the first update came in the form of version 6.01, which was a minor update, mainly correcting bugs. * Version 6.10, released on October 27, 2003, introduced several user interface and usability improvements, considerably optimized performance, and slightly improved page rendering. It was also the first version to support proxy servers, WAP pages, and the first one to be released in localized versions for 9 different languages. * On July 13, 2005, almost two years after the previous iteration, version 8.0 was launched. This version was the first to require Symbian OS 7 (p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presto (layout Engine)
Presto was the browser engine of the Opera web browser from the release of Opera 7 on 28 January 2003, until the release of Opera 15 on 2 July 2013, at which time Opera switched to using the Blink engine that was originally created for Chromium. Presto was also used to power the Opera Mini and Opera Mobile browsers. Presto is a dynamic engine. Web pages can be re-rendered completely or partially in response to DOM events. Its releases saw a number of bug fixes and optimizations to improve the speed of the ECMAScript (JavaScript) engine. It is proprietary and only available as a part of the Opera browsers. ECMAScript engines A succession of ECMAScript engines have been used with Opera. (For the origin of their names, see Cultural notes below). Pre-Presto versions of Opera used the Linear A engine. Opera versions based on the Core fork of Presto, Opera 7.0 through 9.27, used the Linear B engine. The Futhark engine is used in some versions on the Core 2 fork of Presto, namel ...

Trident (layout Engine)
Trident (also known as MSHTML) is a proprietary browser engine for the Microsoft Windows version of Internet Explorer, developed by Microsoft. MSHTML debuted with the release of Internet Explorer 4 in 1997. For versions 7 and 8 of Internet Explorer, Microsoft made significant changes to MSHTML's layout capabilities to improve compliance with Web standards and add support for new technologies. MSHTML will continue to receive security updates for the IE mode of Microsoft Edge until at least 2029. However, support for new Web standards will not be added. Use in software development MSHTML was designed as a software component to allow software developers to easily add web browsing functionality to their own applications. It presents a COM interface for accessing and editing web pages in any COM-supported environment, like C++ and .NET. For instance, a web browser control can be added to a C++ program and MSHTML can then be used to access the page currently displayed in the web bro ...

Gecko (layout Engine)
Gecko is a browser engine developed by Mozilla. It is used in the Firefox browser, the Thunderbird email client, and many other projects. Gecko is designed to support open Internet standards, and is used by different applications to display web pages and, in some cases, an application's user interface itself (by rendering XUL). Gecko offers a rich programming API that makes it suitable for a wide variety of roles in Internet-enabled applications, such as web browsers, content presentation, and client/server. Gecko is written in C++ and JavaScript, and, since 2016, additionally in Rust. It is free and open-source software subject to the terms of the Mozilla Public License version 2. Mozilla officially supports its use on Android, Linux, macOS, and Windows. History Development of the layout engine now known as Gecko began at Netscape in 1997, following the company's purchase of DigitalStyle. The existing Netscape rendering engine, originally written for Netscape Navigator 1.0 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt (framework)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt.

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazon Silk
Amazon Silk is a web browser developed by Amazon. It was launched in November 2011 for Kindle Fire and Fire Phone, and a Fire TV version was launched in November 2017. The addition of Silk to the Echo Show was announced at an Amazon event in September 2018. The browser uses a split architecture where some of the processing is performed on Amazon's servers to improve webpage loading performance. It is based on the open source Chromium project that uses the Blink and V8 engines. Architecture For each webpage, Silk decides which browser subsystems (networking, HTML or page rendering) to run locally on the device and which to run remotely on its own Amazon EC2 servers. Silk uses Google's SPDY protocol to speed up loading of web pages. Silk gives SPDY performance improvements for non-SPDY optimized websites if the pages are sent through Amazon's servers. Some early reviewers found that cloud-based acceleration did not necessarily improve page loading speed, most notably on faste ...
