caching

问题 Care: No code here, only text and some questions about bitmap caching I'm currently developing an App which is almost finished. The only thing left, that I would like to do is caching images. Because, at the moment, when the user opens the app the app downloads images from a server. Those images are not static, that means they can change every minute/hour/day. I don't know when they change, because it's a list of images gathered by the amount of twitter shares, facebook likes etc. That means,

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 3 years ago . Im new in web development. I just want to ask if how to force clean all cache in the browser using PHP . 回答1: The best you can do is set a cache-control header, but you cannot "force" anything on client with a server-side language. In laravel: return view('some_template')->header('Cache-Control',

问题 I want my site to benefit from being cached but the site is updated pretty often. How can I make sure the user is getting the most recent version? Currently my .htaccess file looks like this: <IfModule mod_expires.c> # Enable expirations ExpiresActive On # Default directive ExpiresDefault "access plus 1 month" # My favicon ExpiresByType image/x-icon "access plus 1 year" # Images ExpiresByType image/gif "access plus 1 month" ExpiresByType image/png "access plus 1 month" ExpiresByType image/jpg

问题 Currently I am using 'Session' to keep the datatables in memory. But after doing few R&Ds, I came to know the it is not a good practice e.g. Session("Syllabus") = RegistartionLogic.GetSyllabusInfo(Session("StudentID")) Requirement: The items of dropdown will be different based on student-type. The dropdown data will be fetched from DB and these controls are used in more than one screen. Multiple DB call is not preferred from different screens for same data. So I need to call only one DB call,

问题 I am try to create an iOS app, that have a UIWebview and I want to load the website inside it. I try to use EVURLCache for caching. But it doesn't load from the PreCache folder inside my project. The app run first time fine. But when I try to run again it shows me blank screen only. I think the app try to load the page from the cache, but the app can't find its caches..

问题 So I have an app that caches geopoints per user and then saves it on Parse.com and then updates my map with last known coordinates of all users. But it crashes and I can't find the reason why. It will work with manually input lats and longitudes, but not caches current lats and long. This is my method for it; public class MapActivity extends FragmentActivity implements LocationProvider.LocationCallback { public static final String TAG = MapActivity.class.getSimpleName(); ParseUser currentUser

问题 When I try to make a jquery ajax "Type:Post" request, I get an 404 not found (from cache) error. I've tried several workarounds to fix this problem but it doesn't worked. This are the workarounds I've tried: Adding header information in ajax call: "Cache-Control" : "private, no-cache, no-store, must-revalidate", "Expires" : "0", jquery ajax "cache:false" add rnd URL param, "?nocache=' + new Date().getTime()", tried to disable AppCache (nativ): "super.appView.getSettings().setAppCacheEnabled

问题 I have a complex variable {{course_type.title[language] | nl2br}} in my custom block template. language is the current sites language but the content is only delivered in the language of the time, when the cache was build. I do have languages in my render array and it works for {% trans %} commands in the twig template: return array( '#theme' => 'block__vt_course_offer', '#data' => $courseData, '#cache' => [ 'contexts' => ['languages'], 'tags' => $cacheTags, ] ); Is there a way to get Drupal

问题 This is a follow-up to this question, which contains contradictory answers. I am also interested in an answer related to a more recent version of ASP.NET. My application uses HttpRuntime.Cache to cache some lists of models that should never expire. They are loaded on application warmup and they are changed quite rarely, but read quite often. My code is the following: private void ReportRemovedCallback(string key, object value, CacheItemRemovedReason reason) { if (!ApplicationPoolService
