caching

问题 I am using camel 2.18.1 and the camel-ehcache component to build a simple cache. While the cache setup is working okay, I am finding it difficult to register mbeans using ehcache 3.1.2 ( this is pulled in via camel). Reading the documentations - it is not clear how one would enable support with 3.x as the standard way of registering mbeans using ManagementService is no longer available on the API. The documentation is a bit confusing with pure ehcache implementations and JSR-107 cache

问题 I do the following in my pipeline - bash: | $ANDROID_SDK_ROOT/tools/bin/sdkmanager 'ndk;20.0.5594570' >/dev/null $ANDROID_SDK_ROOT/tools/bin/sdkmanager 'ndk;21.0.6113669' >/dev/null displayName: "install NDK" Which takes about 3 minutes I was wondering if I can cache this to speed things up. However, I am not sure where it puts the files. 回答1: It seems you want to cache ndk.

问题 Say you're HTTP caching a login protected page (not critical banking info). Now because you're using HTTP caching, logging out (destroying the session) will not have an effect on that cached page. Currently, the only way I can think of is to explicitly set a sensible max-age cache value so it at least expires at some point. E.g., members_area.php \header('Cache-Control: max-age=60'); Other than this, are there better ways to invalidate memebrs_area.php in the user's browser when they click

问题 I have this ingress configuration but all html and json reponse pages dont contain the added header: apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: {{ $app }}-ingress labels: app: {{ $app }} chart: chart-{{ $app }} app.kubernetes.io/managed-by: Helm annotations: meta.helm.sh/release-name: {{ $app }} meta.helm.sh/release-namespace: {{ .Release.Namespace }} kubernetes.io/ingress.class: nginx nginx.ingress.kubernetes.io/proxy-body-size: "{{ $proxy_body_size }}" nginx.ingress

问题 Right now I have OutCache on an action with duration set to 365 days. However depending on some events I would like to clear the cache and there are multiple conditions for clearing cache. Moreover, VaryByParam is not an option. How can I achieve this? I think I can do something like this, store a variable in cookie like: RefreshCache = false and check this in VaryByCustom override method. Incase the RefreshCache evaluates to true, reset it to false, increment VaryByCustom argument variable

问题 I'm using Caffeine Cache library for Spring Cache. Is there a way to get all the cached keys? My current application works on a near-realtime data, with the flow as : In the Cache Updater Thread (which runs at a fixed interval, irrespective of the user request), I need to get all the keys currently in the Cache, fetch their latest data from Db & then use @CachePut to update the cache. 回答1: Yo can inject CacheManager and obtain native cache from it. @AllArgsConstructor class Test { private

问题 Here is my scenario. I am using WebView to show my mobile-ready website inside an app. We regularly update our website and automatically clear our website cache, so visitors get the latest version of our website instead of stale versions. I've noticed that sometimes WebView is serving old content -- it sometimes doesn't load newer versions of our website. Hence, I'm looking for a way to force WebView to show new content. I know I could totally disable WebView cache and force it to grab the

问题 Our asp.net web application allows our (large) .css and .js files to be cached by client browsers for faster performance. But whenever we deploy a new version, we get phone calls from users about how the page looks messy and is full of javascript errors. It turns out, their browser didn't re-download the changed .css and .js files. Ctrl-F5 always fixes it. Is there any way to force a re-download after upgrade deployments, without setting it not to cache (and thus slowing our application down)
