HTTP 305
Hypertext Transfer Protocol (HTTP) response status codes are issued by a server in response to a client's request made to the server. It includes codes from IETF Request for Comments (RFCs), other specifications, and some additional codes used in some common applications of the HTTP. The first digit of the status code specifies one of five standard classes of responses. The optional message phrases shown are typical, but any human-readable alternative may be provided, or none at all. Unless otherwise stated, the status code is part of the HTTP standard. The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two digits do not have any classifying or categorization role. There are five classes defined by the standard: * ''1xx informational response'' – the request was rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTTP 303
The HTTP response status code 303 See Other is a way to redirect web applications to a new URI, particularly after a HTTP POST has been performed, since RFC 2616 (HTTP 1.1). According to RFC 7231, which obsoletes RFC 2616, "A 303 response to a GET request indicates that the origin server does not have a representation of the target resource that can be transferred by the server over HTTP. However, the Location field value refers to a resource that is descriptive of the target resource, such that making a retrieval request on that other resource might result in a representation that is useful to recipients without implying that it represents the original target resource." This status code should be used with the location header, as described below. If a server responds to a POST or other non-idempotent request with a ''303 See Other'' response and a value for the location header, the client is expected to obtain the resource mentioned in the location header using the GET method; ...

GNU Taler
GNU Taler is a free software-based microtransaction and electronic payment system. Unlike most other decentralized payment systems, GNU Taler does not use a blockchain. A blind signature is used to protect the privacy of users as it prevents the exchange from knowing which coin it signed for which customer. The project is led by Florian Dold and Christian Grothoff of Taler Systems SA. Taler is short for the "Taxable Anonymous Libre Economic Reserves" and alludes to the Taler coins in the Holy Roman Empire during the Early Modern period. It has vocal support from GNU Project founder Richard Stallman. Stallman has described the program as "designed to be anonymous for the payer, but payees are always identified." In a paper published in ''Security, Privacy, and Applied Cryptography Engineering'', GNU Taler is described as meeting ethical considerations – the paying customer is anonymous while the merchant is identified and taxable. An implementation is provided by Taler Sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micropayment
A micropayment is a financial transaction involving a very small sum of money and usually one that occurs online. A number of micropayment systems were proposed and developed in the mid-to-late 1990s, all of which were ultimately unsuccessful. A second generation of micropayment systems emerged in the 2010s. While micropayments were originally envisioned to involve very small sums of money, practical systems to allow transactions of less than 1 have seen little success. One problem that has prevented the emergence of micropayment systems is a need to keep costs for individual transactions low, which is impractical when transacting such small sums even if the transaction fee is just a few cents. Definition There are a number of different definitions of what constitutes a micropayment. PayPal defines a micropayment as a transaction of less than £5 while Visa defines it as a transaction under 20 Australian dollars. History The term was coined by Ted Nelson, long before the invent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Cash
Digital currency (digital money, electronic money or electronic currency) is any currency, money, or money-like asset that is primarily managed, stored or exchanged on digital computer systems, especially over the internet. Types of digital currencies include cryptocurrency, virtual currency and central bank digital currency. Digital currency may be recorded on a distributed database on the internet, a centralized electronic Database, computer database owned by a company or bank, within Computer file, digital files or even on a stored-value card. Digital currencies exhibit properties similar to traditional currencies, but generally do not have a classical physical form of Fiat money, fiat currency historically that can be held in the hand, like currencies with printed banknotes or minted coins. However, they do have a physical form in an unclassical sense coming from the computer to computer and computer to human interactions and the information and processing power of the serv ...

HTTP 402
HTTP Status Code 402, also known as "Payment Required," is a standard response code in the Hypertext Transfer Protocol (HTTP). It is part of the HTTP/1.1 protocol defined by the Internet Engineering Task Force (IETF) in the RFC 7231 specification. Description The HTTP 402 status code indicates that the client must make a payment to access the requested resource. It is typically used in situations where the server requires payment before granting access to the content or service. This code serves as a reminder that financial transaction or authorization is needed to proceed further. The 402 status code is considered non-standard and was introduced to extend the HTTP protocol's capabilities beyond the standard set of status codes. It provides a clear indication to the client that they need to take action to complete the payment process before they can access the requested resource. Examples Client request: GET /index.php HTTP/1.1 Host: www.example.org Server response: HTTP/1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digest Access Authentication
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history. It applies a hash function to the username and password before sending them over the network. In contrast, basic access authentication uses the easily reversible Base64 encoding instead of hashing, making it non-secure unless used in conjunction with TLS. Technically, digest authentication is an application of cryptographic hashing with usage of nonce values to prevent replay attacks. It uses the HTTP protocol. DIGEST-MD5 as a SASL mechanism specified by is obsolete since July 2011. Overview Digest access authentication was originally specified by (''An Extension to HTTP: Digest Access Authentication''). RFC 2069 specifies roughly a traditional digest authentication scheme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Access Authentication
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials>, where <credentials> is the Base64 encoding of ID and password joined by a single colon :. It was originally implemented by Ari Luotonen at CERN in 1993 and defined in the HTTP 1.0 specification in 1996. It is specified in from 2015, which obsoletes from 1999. Features HTTP Basic authentication (BA) implementation is the simplest technique for enforcing access controls to web resources because it does not require cookies, session identifiers, or login pages; rather, HTTP Basic authentication uses standard fields in the HTTP header. Security The BA mechanism does not provide confidentiality protection for the transmitted credentials. They are merely encoded with Base64 i ...

Internet Explorer
Internet Explorer (formerly Microsoft Internet Explorer and Windows Internet Explorer, commonly abbreviated as IE or MSIE) is a deprecation, retired series of graphical user interface, graphical web browsers developed by Microsoft that were used in the Microsoft Windows, Windows line of operating systems. While IE has been discontinued on most Windows editions, it remains supported on certain editions of Windows, such as Windows 10 editions#Organizational editions, Windows 10 LTSB/LTSC. Starting in 1995, it was first released as part of the add-on package Microsoft Plus!, Plus! for Windows 95 that year. Later versions were available as free downloads or in-service packs and included in the original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows. Microsoft spent over per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999. In 2016, Microsoft Edge (series of web browsers), Microsoft Edge w ...
