caching

问题 I've read lots of posts about caching already, but none of them actually match my needs exactly. In my mvc 3 app I have an action method GetImage() that returns a File of image type. Then I use this method in a view to display image: <img width="75" height="75" src="@Url.Action("GetImage", "Store", new {productId = item.ProductId})"/> I want to cache images on a Server. So, what I've already tried: 1) to use OutputCacheAttribute: [HttpGet, OutputCache(Duration = 10, VaryByParam = "productId",

问题 I am looking for a simple in-memory (and in-process) cache for short-term caching of query data (but short-term meaning beyond request/response, i.e. session boundary). EhCache would probably work, but it looks as if it might not offer one thing that I need: limits not on number of objects cached, but (approximate) limit on amount of memory consumed by cached data. I understand that it is hard to figure out exact memory usage for given object without serialization (which I want to avoid in

问题 I have a unique problem, which is proving difficult to solve using google. I am consolidating all of my javascript and css into separate php files, which use require_once() to pull the contents of the files in. The javascript file looks something like this: <?php header('Content-Type: text/javascript'); require_once('jquery.form.js'); require_once('jquery.jqtransform.js'); require_once('jquery.validate.js'); ?> My specific problem is that web browsers will 'see' that this is a dynamic page,

问题 I have a WebView in which I can access to web pages. Is it possible, when I am offline to have access for example to the images that have been previously downloaded? And if it is possible how can I do this? Thanks in advance. 回答1: Yes, you can, at least for Android 2.3 and lower. If you want to see the entire cache folder, it is situated here: <android cache dir>/<your app package>/cache/webviewCache/ If you already know the URL of the cached image, you can get the actual file so: String uri

问题 I'm trying to integrate the Angular Service Worker into a existing project. If I understood it correctly there are two cases how data gets cached in Angular SW. It is possible to prefetch or lazyupdate the asset data and to cache specific API calls and other XHR requests. What I'm trying to achieve is to load an specific asset first via network, if the request runs into a timeout or is not accessible it will be served via the cache. Just like the freshness strategy when caching API calls. But

问题 I am storing a single integer value in HttpContext.Cache with an absolute expiration time of 5 minutes from now. However, after waiting 6 minutes (or longer), the integer value is still in the Cache (i.e. it's never removed even though the absolute expiration has passed). Here is the code I am using: public void UpdateCountFor(string remoteIp) { // only returns true the first time its run // after that the value is still in the Cache // even after the absolute expiration has passed // so

问题 I'm trying to disable the cache in my AngularJS app, but it isn't working with the following code: $http.get("myurl",{cache:false}) When I use "myurl&random="+Math.random() , the cache is disabled; but, I'd like a different approach. 回答1: This is already answered here. Pasting code snippet from the link for your reference. myModule.config(['$httpProvider', function($httpProvider) { //initialize get if not there if (!$httpProvider.defaults.headers.get) { $httpProvider.defaults.headers.get = {}

问题 After attempting to setup git credential cache on Windows 7 I would now like to scrap the idea and remove this error message and setting from git. git: 'credential-cache' is not a git command. This related question shows how to fix this error by installing additional software to make the credential caching work -- I however wish to remove this setting all together. How do I do this? I have tried: git config --global --remove-section credential-cache and variations thereof. Also it does not

问题 I'd like to cache a fragment view. My Activity has swipeable tabs and each tab calls a different fragment. But when i swipe between tabs the transition seems a quite slow because of the destruction of the fragment view, that is rebuilded during the swipe operation. Does anyone know how can i cache the view of each fragment to prevent this issue? I work with library support v4 and api 14 I tried to implement a constructor for the fragments, called by the activity container of the fragments: i
