Query: When was the first web page released?
The first web page may be lost, but Paul Jones of UNC-Chapel Hill in North Carolina revealed in May 2013 that he has a copy of a page sent to him in 1991 by Berners-Lee which is the oldest known web page. Jones stored the plain-text page, with hyperlinks, on a floppy disk and on his NeXT computer.[15] CERN put the oldest known web page back online in 2014, complete with hyperlinks that helped users get started and helped them navigate what was then a very small web.[16][17]
A web beacon (also called web bug, tracking bug, tag, web tag, page tag, tracking pixel, pixel tag, 1×1 gif, or clear gif) is one of various techniques used on web pages or email, to unobtrusively (usually invisibly) allow checking that a user has accessed some content. Web beacons are typically used by third parties to monitor the activity of users at a website for the purpose of web analytics or page tagging. They can also be used for email tracking. When implemented using JavaScript, they may be called JavaScript tags.
Electronic pages displayed on a web browser are often called web pages, regardless of whether they are accessed online via a web server on the World Wide Web, or stored locally offline. More accurately, such documents are named by the markup language that makes them displayable via a web browser, e.g. "HTML page" or "PHP page". With dynamic web pages, pagination is used for such things as displaying a limited number of results on search engine results pages, or showing a limited number of posts when viewing a forum thread. Pagination is used in some form in almost every web application to divide returned data and display it on multiple pages. Pagination also includes the logic of preparing and displaying the links to the various pages.
When printing a web page, the ease of printing depends on the length of the page, compared to shorter web pages with pagination. In longer web pages which have infinite scrolling (for example, Facebook, LinkedIn and Twitter), it is harder to print all pages as the total number of upcoming pages is unknown. Therefore, users can only print loaded pages in web pages which use infinite scrolling.
The first web browser, called WorldWideWeb, was invented in 1990 by Sir Tim Berners-Lee. He then recruited Nicola Pellow to write the Line Mode Browser, which displayed web pages on dumb terminals; it was released in 1991.
Bing Translator can translate phrases entered by the user or acquire a link to a web page and translate its entirely. When translating an entire web page, or when the user selects "Translate this page" in Bing search results, the Bilingual Viewer is shown, which allows users to browse the original web page text and translation in parallel, supported by synchronized highlights, scrolling, and navigation. Four Bilingual Viewer layouts are available: side by side, top and bottom, original with hover translation and translation with hover original.
Web scraping a web page involves fetching it and extracting from it. Fetching is the downloading of a page (which a browser does when you view the page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Once fetched, then extraction can take place. The content of a page may be parsed, searched, reformatted, its data copied into a spreadsheet, and so on. Web scrapers typically take something out of a page, to make use of it for another purpose somewhere else. An example would be to find and copy names and phone numbers, or companies and their URLs, to a list (contact scraping).
The program code lies inactive on a web server until a user (client) requests a web page that contains a link to the code using the client's web browser. Upon this request, the web page and the program are transported to the user's machine using HTTP. When the page is displayed, the code is started in the browser and executes locally, inside the user's computer until it is stopped (e.g., by the user leaving the web page).
As of 2021, Bing Translator offers translations in different language systems.
Bing Translator can translate phrases entered by the user or acquire a link to a web page and translate its entirely. When translating an entire web page, or when the user selects "Translate this page" in Bing search results, the Bilingual Viewer is shown, which allows users to browse the original web page text and translation in parallel, supported by synchronized highlights, scrolling, and navigation. Four Bilingual Viewer layouts are available:
A "static" web page is delivered exactly as stored, as web content in the web server's file system. In contrast, a "dynamic" web page is generated by a web application, usually driven by server-side software. Dynamic web pages help the browser (the client) to enhance the web page through user input to the server.
ETag values can be used in web page monitoring systems. Efficient web page monitoring is hindered by the fact that most websites do not set the ETag headers for web pages. When a web monitor has no hints whether web content has been changed all content has to be retrieved, and analyzed, using computing resources for both the publisher and subscriber.
In contrast, web applications use web documents written in a standard format such as HTML and JavaScript, which are supported by a variety of web browsers. Web applications can be considered as a specific variant of client–server software where the client software is downloaded to the client machine when visiting the relevant web page, using standard procedures such as HTTP. Client web software updates may happen each time the web page is visited. During the session, the web browser interprets and displays the pages, and acts as the "universal" client for any web application.
For dynamically created web pages, Google proposes the above meta tag which causes fragment URLs (ones that look like "http://www.url.com/#xyz" ) to be rewritten and recrawled as "ugly URLs" (i.e. ones looking like "http://www.url.com/?_escaped_fragment_=xyz" ). See for more details about the rewriting process. This rewrite step is a signal to the web site to please provide a simple and full HTML web page that is the result of executing the AJAX or other scripting on the page. This allows Google and other search engines to collect and index static web pages even when a web page is dynamically created and updated by the browser.
The first web browser, WorldWideWeb, was developed in 1990 by Tim Berners-Lee for the NeXT Computer (at the same time as the first web server for the same machine) and introduced to his colleagues at CERN in March 1991. Berners-Lee recruited Nicola Pellow, a math student intern working at CERN, to write the Line Mode Browser a cross-platform web browser that displayed web-pages on old terminals and was released in May 1991.
Python Server Pages (PSP) is a name used by several different implementations of server-side script engines for creating dynamically-generated web pages by embedding Python in HTML. For example, an implementation of Python Server Pages was released with mod_python 3.1 in 2004.
Spyce, which also claims the phrase "Python Server Pages", was first released in 2002.
The Webware for Python suite also contains an implementation of Python Server Pages released as early as 2000.
An earlier tool with a similar function also called Python Server Pages but based on Java and JPython was first released in 1999.
When creating a web page, it is important to ensure it conforms to the World Wide Web Consortium (W3C) standards for HTML, CSS, XML and other standards. The W3C standards are in place to ensure all browsers which conform to their standards can display identical content without special consideration for proprietary rendering techniques. A properly coded web page is going to be accessible to many different browsers old and new alike, display resolutions, as well as those users with audio or visual impairments.
The Uniform Resource Locator is also called as URL. Web pages are typically becoming more dynamic. A dynamic web page is one that is created server-side when it is requested and then served to the end-user. These types of web pages typically do not have a permalink, or a static URL, associated with them. This practice is intended to reduce the amount of static pages in lieu of storing the relevant web page information in a database. This can be seen in forums, online shopping websites, and on Wikipedia. Some search engines may have a hard time indexing a web page that is dynamic, so static web pages can be provided in those instances.
Another feature of Enonic XP is the possibility for developers to create progressive web apps (PWA). A PWA is a web application that is a regular web page or website, but can appear to the user like a mobile application. In early 2017 Enonic released “Office League”, an open-source progressive web application built on the Enonic XP platform, making it one of the first companies in Scandinavia to develop and release a production-ready PWA. Later in 2017 Enonic released a PWA starter kit, helping developers build scalable PWAs in Enonic XP.
A static web page (sometimes called a flat page/stationary page) is a web page that is delivered to the user exactly as stored, in contrast to dynamic web pages which are generated by a web application.
Web searching could be dramatically improved by the development of a controlled vocabulary for describing Web pages; the use of such a vocabulary could culminate in a Semantic Web, in which the content of Web pages is described using a machine-readable metadata scheme. One of the first proposals for such a scheme is the Dublin Core Initiative. An example of a controlled vocabulary which is usable for indexing web pages is PSH.
Dynamic web pages are often cached when there are few or no changes expected and the page is anticipated to receive considerable amount of web traffic that would create slow load times for the server if it had to generate the pages on the fly for each request.
URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened. Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as when wikipedia.com and wikipedia.net are automatically redirected to wikipedia.org. URL redirection is done for various reasons: for URL shortening; to prevent broken links when web pages are moved; to allow multiple domain names belonging to the same owner to refer to a single web site; to guide navigation into and out of a website; for privacy protection; and for hostile purposes such as phishing attacks or malware distribution.
In computing, the same-origin policy is an important concept in the web application security model. Under the policy, a web browser permits scripts contained in a first web page to access data in a second web page, but only if both web pages have the same "origin". An origin is defined as a combination of URI scheme, host name, and port number. This policy prevents a malicious script on one page from obtaining access to sensitive data on another web page through that page's Document Object Model.
Web traffic is measured to see the popularity of websites and individual pages or sections within a site. This can be done by viewing the traffic statistics found in the web server log file, an automatically generated list of all the pages served. A "hit" is generated when any file is served. The page itself is considered a file, but images are also files, thus a page with 5 images could generate 6 hits (the 5 images and the page itself). A "page view" is generated when a visitor requests any page within the website – a visitor will always generate at least one page view (the main page) but could generate many more.
Tracking applications external to the website can record traffic by inserting a small piece of HTML code in every page of the website.
In August 2012 the company released its Page Classifier API, which automatically categorizes web pages into specific "page types". As part of this, Diffbot analyzed 750,000 web pages shared on the social media service Twitter and revealed that photos, followed by articles and videos, are the predominant web media shared on the social network.
Store pages are delivered using standard HTML with a special header. This change was made when iTunes 9.0 was released. iTunes uses WebKit to render these pages on the screen. These pages are also accessible on the Web, at itunes.apple.com, allowing pages from iTunes Store to show up in search engine search results.
