or - The validator is about to be used by a client in an If- Modified-Since or If-Unmodified-Since header, because the client has a cache entry for the associated entity, and now minus date_value, if the local clock is reasonably well synchronized to the origin server's clock. So, we compute: corrected_initial_age = corrected_received_age + (now - request_time) where "request_time" is the time (according to the local clock) when the request that elicited this response was sent. Partial responses MAY be combined as described in section 13.5.4; the result might be a full response or might still be partial. news
Writing a singleton as a countable intersection How to prove that authentication system works, and that the customer is using the wrong password? Note: a response that lacks a validator may still be cached, and served from cache until it expires, unless this is explicitly prohibited by a cache-control directive. The Age field value is the cache's estimate of the amount of time since the response was generated or revalidated by the origin server. If a cache has a stored non-empty set of subranges for an entity, and an incoming response transfers another subrange, the cache MAY combine the new subrange with the existing set
However, in some cases, cache-control directives are explicitly specified as weakening the approximation of semantic transparency (for example, "max-stale" or "public"). Access-Control-Max-Age The Access-Control-Max-Age header indicates how long the results of a preflight request can be cached. The Cache-Control header allows a client or server to transmit a variety of directives in either requests or responses. Note: some HTTP/1.0 caches are known to violate this expectation without providing any Warning.
Bug? If the selecting request header fields for the cached entry do not match the selecting request header fields of the new request, then the cache MUST NOT use a cached entry The Cross-Origin Resource Sharing standard works by adding new HTTP headers that allow servers to describe the set of origins that are permitted to read that information using a web browser. It is "fresh enough" (see section 13.2).
Or even better, you can create page that will receive url as param and do request to that url and just return result. Strong validators are usable in any context. So frustrating. Access-Control-Max-Age:
It also allows the user agent to take steps to obtain a first-hand or fresh response. Still this is not that great solution. For this reason, a cache SHOULD NOT return a stale response if the client explicitly requests a first-hand or fresh one, unless it is impossible to comply for technical or policy In the thread referenced above Juha says that he uses the following code in Django: def send_data(request): if request.method == "OPTIONS": response = HttpResponse() response['Access-Control-Allow-Origin'] = '*' response['Access-Control-Allow-Methods'] = 'POST, GET,
That is, although they might continue to be "fresh," they do not accurately reflect what the origin server would return for a new request on that resource. Thus, we avoid transmitting the full response if the validator matches, and we avoid an extra round trip if it does not match. For example, an HTML page served from http://domain-a.com makes an src request for http://domain-b.com/image.jpg. http://bovbjerg.net/warning-cannot/warning-cannot-yet-handle-mbcs-in-html-entity-decode.php What is the significance of the robot in the sand?

This is either the entity referred to by the Request-URI, or by the Location or Content-Location headers (if present). Warning: unnecessary modification of end-to-end headers might cause authentication failures if stronger authentication mechanisms are introduced in later versions of HTTP. Many pages on the web today load resources like CSS stylesheets, images and scripts from separate domains. Requirements for performance, availability, and disconnected operation require us to be able to relax the goal of semantic transparency.
The Content-Length field of a request or response is added or deleted according to the rules in section 4.4. As a general rule, if there is any apparent conflict between header values, the most restrictive interpretation is applied (that is, the one that is most likely to preserve semantic transparency). The presence of an Age header field in a response implies that a response is not first-hand. This does not prevent a proxy cache from sending a 100 (Continue) response before the inbound server has sent its final reply.
If the user has overridden the caching mechanisms in a way that would abnormally reduce the effectiveness of caches, the user agent SHOULD continually indicate this state to the user (for It sets custom headers in the request (e.g. System.out.println(url+"?wsdl"); Endpoint.publish(url, area); // publishing the webservice } } share|improve this answer answered May 6 '13 at 14:19 madas 33313 Check this link, it may help:stackoverflow.com/questions/4648647/… –Juned Ahsan May In the thread referenced above Juha says that he uses the following code in Django: def send_data(request): if request.method == "OPTIONS": response = HttpResponse() response['Access-Control-Allow-Origin'] = '*' response['Access-Control-Allow-Methods'] = 'POST, GET,
I've spent a good 6 hours today trying to solve this without any luck. Given that we have two independent ways to compute the age of a response when it is received, we can combine these as corrected_received_age = max(now - date_value, age_value) and as
