A server MUST send its responses to those requests in the same order that the requests were received. Section 14.1 work and power pdf answer key ph scale remote lab 2. Authorization will not help and the request SHOULD NOT be repeated. The status codes 303 and 307 have been added for servers that wish to make unambiguously clear which kind of reaction is expected of the client. Warning: unnecessary modification of end-to-end headers might cause authentication failures if stronger authentication mechanisms are introduced in later versions of HTTP.
The force exerted by a machine is called the force. The sample papers and MCQs are provided for better practice with the questions from previous years' question papers. 1 Method The Method token indicates the method to be performed on the resource identified by the Request-URI. Section 14.1 work and power pdf answer key west. Force acting on the object multiplied by the the object moves. These differences were carefully chosen to optimize performance over binary connections, to allow greater freedom in the use of new media types, to make date comparisons easier, and to acknowledge the practice of some early HTTP servers and clients. Note that such authenticated responses also need the public cache control directive in order to allow them to be cached at all.
The set of header fields named by the Vary field value is known as the "selecting" request-headers. 8 TRACE The TRACE method is used to invoke a remote, application-layer loop- back of the request message. Chapter 14Work, Power, and Machines Section … Reading 14.pdfSection 14.1 Work and Power (pages 412–416) This section defines work and power, describes how they are related, and - [PDF Document.

HTTP requests and responses can be pipelined on a connection.
This means that the response is always stale, and so the cache SHOULD validate it before using it for subsequent requests. Physical science 14.1 work and power Flashcards. Ways to maximize mechanical advantage andefficiency are discussed. If a request is authenticated and a realm specified, the same credentials SHOULD be valid for all other requests within this realm (assuming that the authentication scheme itself does not require otherwise, such as credentials that vary according to a challenge value or using synchronized clocks). Although this prevents any media type parameter named "q" from being used with a media range, such an event is believed to be unlikely given the lack of any "q" parameters in the IANA media type registry and the rare usage of any media type parameters in Accept. 1 clients and caches SHOULD assume that an RFC-850 date which appears to be more than 50 years in the future is in fact in the past (this helps solve the "year 2000" problem).
A response received with any other status code (e. status codes 302 and 307) MUST NOT be returned in a reply to a subsequent request unless there are cache-control directives or another header(s) that explicitly allow it. Product = token ["/" product-version] product-version = token Examples: User-Agent: CERN-LineMode/2. Compute T = R * (2**N), where N is the number of previous retries of this request. The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. 1 June 1999 - If only a Last-Modified value has been provided by an HTTP/1. If the user has overridden the basic caching mechanisms, the user agent SHOULD explicitly indicate to the user whenever this results in the display of information that might not meet the server's transparency requirements (in particular, if the displayed entity is known to be stale). A proxy MUST implement both the client and server requirements of this specification. 6 Introduction of Transfer-Encoding HTTP/1.

This is either the entity referred to by the Request-URI, or by the Location or Content-Location headers (if present). 18 Date The Date general-header field represents the date and time at which the message was originated, having the same semantics as orig-date in RFC 822. This field allows clients capable of understanding more comprehensive or special- purpose character sets to signal that capability to a server which is capable of representing documents in those character sets. 13 412 Precondition Failed The precondition given in one or more of the request-header fields evaluated to false when it was tested on the server.
Implementors SHOULD make the Server header field a configurable option. Unlike byte-ranges-specifier values (see section 14. 3 for the use of the 100 (continue) status. For questions 13 through 15, refer to the figure below. Traditional Authority.
1 systems receiving this information will make the most conservative assumptions about the validators they receive. A machines is the mechanicaladvantage in the absence of friction. The HTTP protocol does not place any a priori limit on the length of a URI. 0 cache implementations will treat an Expires value that is less than or equal to the response Date value as being equivalent to the Cache-Control response directive "no-cache". Note: Note to implementors: some deployed proxies are known to return 400 or 500 when DNS lookups time out. 0 m above the ground. 6 205 Reset Content........................................ 7 206 Partial Content...................................... 3 Redirection 3xx............................................. 61 10. Instead, if the request method was GET or HEAD, the server SHOULD respond with a 304 (Not Modified) response, including the cache- related header fields (particularly ETag) of one of the entities that matched. A byte-content-range-spec with a byte-range-resp-spec whose last- byte-pos value is less than its first-byte-pos value, or whose instance-length value is less than or equal to its last-byte-pos value, is invalid. It MUST then add any Warning headers received in the validating response. Holding the barbell over his head? The "chunked" transfer-coding is always acceptable. If the request passes through a cache and the Request-URI identifies one or more currently cached entities, those entries SHOULD be treated as stale. James Watt and Horsepower (page 416)16.
6 Response After receiving and interpreting a request message, a server responds with an HTTP response message. Naturally, it is not possible to ensure that the server does not generate side-effects as a result of performing a GET request; in fact, some dynamic resources consider that a feature.
