Hotlinking
Inline linking (also known as hotlinking, piggy-backing, direct linking, offsite image grabs, bandwidth theft, or leeching) is the practice of using or embedding a linked object—often an image—from one website onto a webpage of another website. In this process, the second site does not host the object itself but instead loads it directly from the original source, creating an inline link to the hosting site. HTTP and inline linking The Hypertext Transfer Protocol (HTTP), the technology behind the World Wide Web, does not differentiate between different types of links—all links are functionally equal. As a result, resources can be linked from any server and loaded onto a web page regardless of their original location. When a website is visited, the browser first downloads the HTML document containing the web page's textual content. This document may reference additional resources, including other HTML files, images, scripts, or stylesheet. Within the HTML, <img> tags s ...

Embedding Rich Media
An HTML element is a type of HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others). The first used version of HTML was written by Tim Berners-Lee in 1993 and there have since been many versions of HTML. The current de facto standard is governed by the industry group WHATWG and is known as the HTML Living Standard. An HTML document is composed of a tree structure, tree of simple HTML Node (computer science), nodes, such as text nodes, and HTML elements, which add semantics and formatting to parts of a document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Concepts Elements vs. tags As is generally understood, the position of an element is indicated as spanning from a start tag and is terminated by an end tag. This is ...

Hit Counter
A web counter or hit counter is a publicly displayed running tally of the number of visits a webpage has received. Web counters are usually displayed as an inline digital image or in plain text. Image rendering of digits may use a variety of fonts and styles, with a classic design imitating the wheels of an odometer. Web counters were often accompanied by the date it was set up or last reset, to provide more context to readers on how to interpret the number shown. Although initially a way to publicly showcase a site's popularity to its visitors, some early web counters were simply web bugs used by webmasters to track hits and included no visible on-page elements. Counters were popular in the 1990s, but were later replaced by other web traffic measures such as self-hosted scripts like Analog, and later on by remote systems that used JavaScript, like Google Analytics. These systems typically do not include on-page elements displaying the count. Thus, seeing a web counter on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
URL Rewriting
In web applications, a rewrite engine is a software component that performs rewriting on URLs (Uniform Resource Locators), modifying their appearance. This modification is called URL rewriting. It is a way of implementing URL mapping or routing within a web application. The engine is typically a component of a web server or web application framework. Rewritten URLs (sometimes known as short, pretty or fancy URLs, search engine friendly - SEF URLs, or slugs) are used to provide shorter and more relevant-looking links to web pages. The technique adds a layer of abstraction between the files used to generate a web page and the URL that is presented to the outside world. Usage Web sites with dynamic content can use URLs that generate pages from the server using query string parameters. These are often rewritten to resemble URLs for static pages on a site with a subdirectory hierarchy. For example, the URL to a wiki page with title ''Rewrite_engine'' might be: http://example.c ...

HTTP Referer
In HTTP, "" (a misspelling of "Referrer") is an optional HTTP header field that identifies the address of the web page (i.e., the URI or IRI) from which the resource has been requested. By checking the referrer, the server providing the new web page can see where the request originated. In the most common situation, this means that when a user clicks a hyperlink in a web browser, causing the browser to send a request to the server holding the destination web page, the request may include the field, which indicates the last page the user was on (the one where they clicked the link). Web sites and web servers log the content of the received field to identify the web page from which the user followed a link, for promotional or statistical purposes. This entails a loss of privacy for the user and may introduce a security risk. To mitigate security risks, browsers have been steadily reducing the amount of information sent in Referer.

Ad Filtering
Ad blocking (or ad filtering) is a software capability for blocking or altering online advertising in a web browser, an application or a network. This may be done using browser extensions or other methods or browsers with inside blocking. History The first ad blocker was Internet Fast Forward, a plugin for the Netscape Navigator browser, developed by PrivNet and released in 1996. The AdBlock extension for Firefox was developed in 2002, with Adblock Plus being released in 2006. uBlock Origin, originally called "uBlock", was first released in 2014. Technologies and native countermeasures Online advertising exists in a variety of forms, including web banners, pictures, animations, embedded audio and video, text, or pop-up windows, and can even employ audio and video autoplay. Many browsers offer some ways to remove or alter advertisements: either by targeting technologies that are used to deliver ads (such as embedded content delivered through browser plug-ins or via HTML ...

Web Bug
A web beaconAlso called web bug, tracking bug, tag, web tag, page tag, tracking pixel, pixel tag, 1×1 GIF, spy pixel, or clear GIF. is a technique used on web pages and 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. Web beacons are unseen HTML elements that track a webpage views. Upon the user revisiting the webpage, these beacons are connected to cookies established by the server, facilitating undisclosed user tracking. Using such beacons, companies and organizations can track the online behavior of web users. At first, the companies doing such tracking were mainly advertisers or web analytics companies; later social media sites also started to use such tracking techniques, ...

Web Visitor Tracking
Web tracking is the practice by which operators of websites and third parties collect, store and share information about visitors' activities on the World Wide Web. Analysis of a user's behaviour may be used to provide content that enables the operator to infer their preferences and may be of interest to various parties, such as advertisers. Web tracking can be part of visitor management. Uses The uses of web tracking include the following: * Advertising companies actively collect information about users and make profiles that are used to individualize advertisements. User activities include websites visited, watched videos, interactions on social networks, and online transactions. Websites like Netflix and YouTube collect information about what shows users watch, which helps them suggest more shows that they might like. Search engines like Google will keep a record of what users search for, which could help them suggest more relevant searches in the future. * Law enforcement agen ...

Security Bug
A security bug or security defect is a software bug that can be exploited to gain unauthorized access or privileges on a computer system. Security bugs introduce security vulnerabilities by compromising one or more of: * Authentication of users and other entities * Authorization of access rights and privileges * Data confidentiality * Data integrity Security bugs do not need be identified nor exploited to be qualified as such and are assumed to be much more common than known vulnerabilities in almost any system. Causes Security bugs, like all other software bugs, stem from root causes that can generally be traced to either absent or inadequate: * Software developer training * Use case analysis * Software engineering methodology * Quality assurance testing * and other best practices Taxonomy Security bugs generally fall into a fairly small number of broad categories that include: * Memory safety (e.g. buffer overflow and dangling pointer bugs) * Race condition * Secure ...

Client (computing)
is a computer that gets information from another computer called server in the context of client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. A client is a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which may or may not be located on another computer). For example, web browsers are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers. Online chat uses a variety of clients, which vary on the chat protocol being used. Multiplayer video games or online video games may run as a client on each computer. The term "client" may also be applied to computers or devices that run the client software or users that use the client software. A client is part of a cl ...

Drive-by Download
In computer security, a drive-by download is the unintended download of software, typically Malware, malicious software. The term "drive-by download" usually refers to a download which was authorized by a user without understanding what is being downloaded, such as in the case of a Trojan horse (computing), Trojan horse. In other cases, the term may simply refer to a download which occurs without a user's knowledge. Common types of files distributed in drive-by download attacks include Computer virus, computer viruses, spyware, or crimeware. Drive-by downloads may happen when visiting a website, opening an Email attachment, e-mail attachment, clicking a link in an email, or clicking on a deceptive pop-up window. Users often click on a pop-up window in the mistaken belief that, for example, an error message from the computer's operating system is being acknowledged or a seemingly innocuous advertisement pop-up is being dismissed. In such cases, the "supplier" may claim that the us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
