Consequently, a static web page displays the same information for all users, from all contexts, subject to modern capabilities of a web server to negotiate content-type or language of the document where such versions are available and the server is configured to do so. A server-side dynamic web page is a web page whose construction is controlled by an application server processing server-side scripts. In server-side scripting, parameters determine how
440-588: A web page on the World Wide Web normally begins either by typing the URL of the page into a web browser or by following a hyperlink to that page or resource. The web browser then initiates a series of background communication messages to fetch and display the requested page. In the 1990s, using a browser to view web pages—and to move from one web page to another through hyperlinks—came to be known as 'browsing,' 'web surfing' (after channel surfing ), or 'navigating

The database was originally intended for use by the Office of the Parliamentary Counsel , but following testing with the public service it was decided to make it available to legal practitioners and the private sector on a commercial basis, as well as to public libraries and Citizens Advice Bureaux . The original database consisted of an Interleaf editorial system which allowed legislation to be held and edited in SGML . In 1991 there were no plans to make

The term web page usually refers to what is visible, but may also refer to the contents of the computer file itself, which is usually a text file containing hypertext written in HTML or a comparable markup language . Typical web pages provide hypertext for browsing to other web pages via hyperlinks , often referred to as links . Web browsers will frequently have to access multiple web resource elements, such as reading style sheets , scripts , and images, while presenting each web page. On

With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links , quotes and other items. HTML elements are delineated by tags , written using angle brackets . Tags such as < img /> and < input /> directly introduce content into

Client-side-scripting, server-side scripting, or a combination of these make for the dynamic web experience in a browser. JavaScript is a scripting language that was initially developed in 1995 by Brendan Eich , then of Netscape , for use within web pages. The standardised version is ECMAScript . To make web pages more interactive, some web applications also use JavaScript techniques such as Ajax ( asynchronous JavaScript and XML ). Client-side script

The formal go-live date was several months later (according to the Central Computer and Telecommunications Agency (CCTA) this was February 1998). The main drivers behind the development of GSi was the plethora of inter-agency connections in UK government which made managing security and connectivity budgets problematic. GSi not only provided better oversight, it also normalised connectivity. GSi
6336-458: The request and response. The HTTP protocol is fundamental to the operation of the World Wide Web, and the added encryption layer in HTTPS is essential when browsers send or retrieve confidential data, such as passwords or banking information. Web browsers usually automatically prepend http:// to user-entered URIs, if omitted. A web page (also written as webpage ) is a document that is suitable for
6424-431: The request it sends an HTTP response back to the browser indicating success: followed by the content of the requested page. Hypertext Markup Language ( HTML ) for a basic web page might look like this: The web browser parses the HTML and interprets the markup ( < title > , < p > for paragraph, and such) that surrounds the words to format the text on the screen. Many web pages use HTML to reference
6512-421: The same site; others require one form or the other, or they may map to different web sites. The use of a subdomain name is useful for load balancing incoming web traffic by creating a CNAME record that points to a cluster of web servers.

This lookup returns an IP address such as 203.0.113.4 or 2001:db8:2e::7334 . The browser then requests the resource by sending an HTTP request across the Internet to the computer at that address. It requests service from a specific TCP port number that is well known for
6776-625: The text, it helped to confirm the validity of his concept. The model was later popularized by Apple 's HyperCard system. Unlike Hypercard, Berners-Lee's new system from the outset was meant to support links between multiple databases on independent computers, and to allow simultaneous access by many users from any computer on the Internet. He also specified that the system should eventually handle other media besides text, such as graphics, speech, and video. Links could refer to mutable data files, or even fire up programs on their server computer. He also conceived "gateways" that would allow access through
6864-441: The two terms do not mean the same thing. The Internet is a global system of computer networks interconnected through telecommunications and optical networking . In contrast, the World Wide Web is a global collection of documents and other resources , linked by hyperlinks and URIs . Web resources are accessed using HTTP or HTTPS , which are application-level Internet protocols that use the Internet transport protocols. Viewing
6952-465: The web pages (or URLs) the directed edges between them to the hyperlinks. Over time, many web resources pointed to by hyperlinks disappear, relocate, or are replaced with different content. This makes hyperlinks obsolete, a phenomenon referred to in some circles as link rot, and the hyperlinks affected by it are often called "dead" links . The ephemeral nature of the Web has prompted many efforts to archive websites. The Internet Archive , active since 1996,
7040-498: The website of the Office of Public Sector Information (OPSI) to form a single "UK Legislation" website. In addition, a "table of effects" has been published every year since 2002 which lists all the legislation repealed, the effects of primary and secondary legislation brought into force since 2002 on primary legislation in the database. The database content includes the following primary legislation in Other primary legislation that
7128-417: The working title 'Firebird' in early 2003, from an earlier practice in browsers such as Lynx . It is reported that Microsoft was granted a US patent for the same idea in 2008, but only for mobile devices. The scheme specifiers http:// and https:// at the start of a web URI refer to Hypertext Transfer Protocol or HTTP Secure , respectively. They specify the communication protocol to use for
7216-487: The world's dominant information systems platform . It is the primary tool that billions of people worldwide use to interact with the Internet. The Web was invented by English computer scientist Tim Berners-Lee while working at CERN . He was motivated by the problem of storing, updating, and finding documents and data files in that large and constantly changing organization, as well as distributing them to collaborators outside CERN. In his design, Berners-Lee dismissed
7304-502: The years 1985 to 1995, though this was quickly removed. In 2004, it was announced that the system designed by Syntegra would be modernised by replacing its editorial database, developing two new enquiry systems (one for government departments (accessible via the Government Secure Intranet , "GSI") and the other for the general public), and the revision and updating of the statute book . Two contracts were signed by
7392-507: Was a success at CERN, and began to spread to other scientific and academic institutions. Within the next two years, there were 50 websites created . CERN made the Web protocol and code available royalty free in 1993, enabling its widespread use. After the NCSA released the Mosaic web browser later that year, the Web's popularity grew rapidly as thousands of websites sprang up in less than
7480-581: Was also the root of the creation of the CESG Listed Adviser Scheme (CLAS). During the build of GSi, the need for accredited advisers became clear as advice on connectivity invariably involved discussing government confidential matters. CESG eventually responded with the above CLAS scheme. GSi was operated on a five-year renewable contract basis. Energis won this contract from Cable & Wireless in August 2003. Cable & Wireless then bought Energis in 2005, thus regaining control over
7568-442: Was designed as an accredited, dual link connected Internet Protocol backbone, it imposed no restrictions on what type of traffic it carried; any restrictions were considered a policy decision for each connecting department. The design of GSi partly supported the then developing eGIF interoperability standards. This was a direct consequence of the two key technical people driving the project, one from Cable & Wireless, one from
7656-719: Was open within the context of its accreditation – it imposed no restrictions on traffic types carried across the network, restrictions and policy control were left to the connecting departments. Email traffic in and out of the network was filtered by an external provider. The concept of GSi was defined by the Cabinet Office , and was turned into practical reality by the Internet Special Products group of Cable & Wireless (then known as Mercury Communications ) at their Brentford premises. GSi development started late 1996, and can be roughly dated by checking
7744-480: Was to enable connected organisations to communicate electronically and securely at low protective marking levels . It was known for the '.gsi.gov.uk' family of domains for government email. Migration away from these domains began in 2019 and will be completed in 2023. Many UK government organisations used the GSi to transfer files on a peer-to-peer (P2P) basis between similarly accredited networks. The network itself
