Features Functionality archive.today can capture individual pages in response to explicit user requests. Since its beginning, archive.today has supported crawling pages with URLs containing the now-deprecated hash-bang fragment (). archive.today records only text and images, excluding XML, RTF, spreadsheet ( xls or ods) and other non-static content. However, videos for certain sites, like Twitter, are saved. It keeps track of the history of snapshots saved, requesting confirmation before adding a new snapshot of an already saved page. Pages are captured at a browser width of 1,024 pixels. CSS is converted to ...

OpenDocument
The Open Document Format for Office Applications (ODF), also known as OpenDocument, is an open file format for word processing documents, spreadsheets, presentations and graphics and using ZIP-compressed XML files. It was developed with the aim of providing an open, XML-based file format specification for office applications. It is also the default format for documents in typical Linux distributions. The standard is developed and maintained by a technical committee in the Organization for the Advancement of Structured Information Standards (OASIS) consortium. It was based on the Sun Microsystems specification for OpenOffice.org XML, the default format for OpenOffice.org and LibreOffice. It was originally developed for StarOffice "to provide an open standard for office documents." In addition to being an OASIS standard, it is published as an ISO/IEC international standard ISO/IEC 26300 Open Document Format for Office Applications (OpenDocument). In 2021 the current ve ...

Web Archiving
Web archiving is the process of collecting portions of the World Wide Web to ensure the information is preserved in an archive for future researchers, historians, and the public. Web archivists typically employ web crawlers for automated capture due to the massive size and amount of information on the Web. The largest web archiving organization based on a bulk crawling approach is the Wayback Machine, which strives to maintain an archive of the entire Web. The growing portion of human culture created and recorded on the web makes it inevitable that more and more libraries and archives will have to face the challenges of web archiving. National libraries, national archives and various consortia of organizations are also involved in archiving culturally important Web content. Commercial web archiving software and services are also available to organizations who need to archive their own web content for corporate heritage, regulatory, or legal purposes. History and development W ...

Static Web Page
A static web page (sometimes called a flat page or a stationary page) is a web page that is delivered to the user's web browser exactly as stored, in contrast to dynamic web pages which are generated by a web application. Consequently, a static web page often 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. However, a site's scripts can introduce dynamic functionality, which may make a static web page appear dynamic. A static web page is a type of web page that is delivered to the user's web browser exactly as it is stored, without any changes or modifications. This is in contrast to dynamic web pages, which are generated by a web application and can change based on user input or other factors. Static web pages are often used to display information that is the same for all users, such as a ...

Robots
"\n\n\n\n\nThe robots exclusion standard, also known as the robots exclusion protocol or simply robots.txt, is a standard used by websites to indicate to visiting web crawlers and other web robots which portions of the site they are allowed to visit.\n\nThis relies on voluntary compliance. Not all robots comply with the standard; email harvesters, spambots, malware and robots that scan for security vulnerabilities may even start with the portions of the website where they have been told to stay out.\n\nThe \"robots.txt\" file can be used in conjunction with sitemaps, another robot inclusion standard for websites.\n History\nThe standard was proposed by Martijn Koster, when working for Nexor in February 1994\n on the ''www-talk'' mailing list, the main communication channel for WWW-related activities at the time. Charles Stross claims to have provoked Koster to suggest robots.txt, after he wrote a badly-behaved web crawler that inadvertently caused a denial-of-service attack on Kost ...

Remote Backup Service
A remote, online, or managed backup service, sometimes marketed as cloud backup or backup-as-a-service, is a service that provides users with a system for the backup, storage, and recovery of computer files. Online backup providers are companies that provide this type of service to end users (or clients). Such backup services are considered a form of cloud computing. Online backup systems are typically built for a client software program that runs on a given schedule. Some systems run once a day, usually at night while computers aren't in use. Other newer cloud backup services run continuously to capture changes to user systems nearly in real-time. The online backup system typically collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers or off-site hardware. There are many products on the market – all offering different feature sets, service levels, and types of encryption. Providers of this type of service frequently target ...

Address Bar
In a web browser, the address bar (also location bar or URL bar) is the element that shows the current URL. The user can type a URL into it to navigate to a chosen website. In most modern browsers, non-URLs are automatically sent to a search engine. In a file browser, it serves the same purpose of navigation, but through the file-system hierarchy. Many address bars offer features like autocomplete and a list of suggestions while the address is being typed in. This auto-completion feature bases its suggestions on the browser's history. Some browsers have keyboard shortcuts to auto-complete an address. Features In addition to the URL, some address bars feature icons showing features or information about the site. For websites using a favicon (a small icon that represents the website), a small icon may be present within the address bar, a generic icon appearing if the website does not specify one. The address bar is also used to show the security status of a web page; various des ...

URL Fragment
In computer hypertext, a URI fragment is a string of characters that refers to a resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier (URI), and the fragment identifier points to the subordinate resource. The fragment identifier introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document. The generic syntax is specified in RFC ((3986))The hash-mark separator in URIs is not part of the fragment Identifier Basics In URIs, a hash mark # introduces the optional fragment near the end of the URL. The generic RFC 3986 syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment, the fragment follows the query. Query parts depend on the URI scheme and are evaluated by the server—e.g., http: supports queries unlike ftp:. Fragments depend on the document MIME type and are eva ...
