http-caching

问题 In my asp.net application, i want to cache some data in the HttpApplicationState . My code to set the data looks like this: Application.Lock(); Application.Set("Name", "Value"); Application.UnLock(); When I read the documentation, it says that HttpApplicationState is implicitly thread safe. But on many blogs it's written that we should use Application.Lock() and Application.Unlock() while writing data to the HttpApplicationState . On the other hand, I could not find any documentation which

问题 I have an application that connect to an external third-party API, and of late the test instance of the API has not been particularly reliable. This stops development progress and turns our build pipelines to red, so I'd like to add an HTTP recording proxy to stop this happening. I've had WireMock recommended, and having tried its record and play features, it does seem to be very good - it pretty much worked out of the box. We simply change the configured URL for the external service, and

问题 Perhaps I'm missing something by not wording my Google searches correctly, but I've run into an issue with IIS 8.5 and caching. I have a server set up that by all standards should be serving only static files. Obviously, when a file is changed, the new file should be served up. The issue is that even after a server restart, setting files to immediately expire, didsabling caching, disabling compression, and turning off any other caching feature, the old file with its old timestamp is still

问题 The current content of this google docs page is: alt text http://www.deviantsart.com/upload/i9k01q.png However, when reading this page with the following PHP fopen() script, I get an older, cached version: (source: deviantsart.com) I've tried two solutions proposed in this question (a random attribute and using POST) and I also tried clearstatcache() but I always get the cached version of the web page. What do I have to change in the following script so that fopen() returns the current

问题 I would like to know how to disable the browser cache, using HTML5. I found this useful post (How to control web page caching, across all browsers?), but it contains the info only for HTML4 or other languages. In my web application I use Java ( Spring Boot ) and Thymeleaf to produce HTML5. I would like to understand what are the equivalent tags for HTML5, of the following HTML tags: <meta http-equiv="Cache-Control" content="no-cache"/> <meta http-equiv="Pragma" content="no-cache"/> <meta http

问题 In our Symfony2 Application we render reusable blocks with render_esi. We have this kind of templates: {% for products as product %} <div class="product"> <h4>{{ product.name }}</h4> <div class="ratings"> {{ render_esi(controller('AcmeDemoCommunityBundle:Rating:ratingStars', { objectType: 'product', objectId: product.id, readOnly: true })) }} </div> </div> {% endfor %} And of cause we use the render_esi also in the detail page of the product. 回答1: I would like to differentiate different types

问题 I am designing a ReST API which follows the basic CRUD pattern. My API can receive a request to update a resource which may take a short time to process. Ideally I would like to inform clients that a new version is about to be available and that there is some uncertainty over when the version I have cached actually expires. So the process I intend to use something like this (improvements welcome): client: GET /some/item myapi: 200 OK last-modified: time-stamp-of-v1 etag: some-hash-relating-to

问题 In PHP, by default no cache related headers are sent. HTTP/1.1 200 OK Date: Fri, 19 Nov 2010 11:02:16 GMT Server: Apache/2.2.15 (Win32) PHP/5.2.9-2 X-Powered-By: PHP/5.2.9-2 Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 26 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: text/html Now, since by default it does not say anything about caching, can it result in say example.com/index.php getting cached in some situations? 回答1: Yes. In general, every successful

问题 I'm attempting to write a curl-like tool that demonstrates the effect of various HTTP caching headers on dot net's HttpClient class. In my initial attempt I'm pointing the tool at one of my internal web services that does not specify any caching information in the response and examining the header of the response. I expect to see that the request is re-sent each time and executed on the server, returning a new but identical set of content each time (for the purpose of this test, the content

问题 Does "Empty Cache and Hard Reload" in Chromium/Chrome empty the entire cache or just parts relevant to the current site? My inkling is that it empties absolutely all cached resources (as suggested in the comment to this answer). However, a definitive answer would be helpful. 回答1: It empties the entire cache. You can verify this with these steps: Browse through a few sites (reddit, stack overflow, ...) Enter chrome://cache into the omnibox Save the list of files Go to a basic website with no
