In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). [1] [2] SQL injection must exploit a security vulnerability in an application's software, for example, when user ...
Code page. In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte. (In some contexts these terms are used more precisely; see Character encoding § Terminology .)
Code injection is the exploitation of a computer bug that is caused by processing invalid data. The injection is used by an attacker to introduce (or "inject") code into a vulnerable computer program and change the course of execution. The result of successful code injection can be disastrous, for example, by allowing computer viruses or ...
In computer science and networking in particular, a session is a time-delimited two-way link, a practical (relatively high) layer in the TCP/IP protocol enabling interactive expression and information exchange between two or more communication devices or ends – be they computers, automated systems, or live active users (see login session ).
On the World Wide Web, HTTP 301 is the HTTP response status code for 301 Moved Permanently. It is used for permanent redirecting, meaning that links or records returning this response should be updated. The new URL should be provided in the Location field, included with the response. The 301 redirect is considered a best practice for upgrading ...
The Main code page ( Russian: Основная кодировка) is an 8-bit code page used in DOS. It was devised in 1986 by a research group at the Academy of Science of the USSR. [1] The other code page by the same group is known as the "Alternative code page" ( Russian: Альтернативная кодировка) which is nearly ...
Experimental. The HTTP status code 402 is currently classified as an experimental code within the HTTP protocol. Such experimental codes are introduced to assess new features or ideas and determine their practical application. The designation of the 402 status implies that a payment is mandated to obtain a particular resource or service.
The substatus codes take the form of decimal numbers appended to the 404 status code. The substatus codes are not officially recognized by IANA and are not returned by non-Microsoft servers. Substatus codes. Microsoft's IIS 7.0, IIS 7.5, and IIS 8.0 servers define the following HTTP substatus codes to indicate a more specific cause of a 404 error:
