caching

问题 I need caching facility which should work from both WCF and from within an ASP .NET app. I have seen: System.Web.Caching.Cache which is not usable from WCF (as I understand it is usable only if service is hosted in IIS, which is not always the case) System.Runtime.Caching which is usable from both of them, but only available from .NET 4, but our .NET version is 3.5. Any suggestions? 回答1: You can absolutely use System.Web.Caching.Cache outside of IIS. Just add a reference to System.Web and

问题 I want to cache some portions of my JSP page because it is heavy to render. The whole page cannot be cached as it contains user specific content, but most of it can. I thought the best solution would be to create a JSP cache tag. It seems there are several solutions for that but most of these projects are dead or abandoned http://www.opensymphony.com/oscache/ http://jakarta.apache.org/taglibs/doc/cache-doc/ http://www.servletsuite.com/servlets/cachetag.htm I am wondering if there is any

问题 Suppose I have a list of all primes, defined as primes :: (Enum α, Integral α) => [α] primes = sieve [2..] where sieve :: (Integral α) => [α] -> [α] sieve [] = undefined sieve (x:xs) = x : (sieve $ filter ((/= 0) . (flip mod x)) xs) and I want to feed primes through multiple, different functions like: sumOfPrimesLessThan :: (Integral α) => α -> α sumOfPrimesLessThan n = sum $ takeWhile (< n) primes or productOfPrimesLessThan :: (Integral α) => α -> α productOfPrimesLessThan n = foldl (*) 1 $

问题 This is the view which is twig that I inject it in the container in Slim: // Views and Templates // https://www.slimframework.com/docs/features/templates.html $container['view'] = function ($container) { $settings = $container->get('settings'); $loader = new Twig_Loader_Filesystem('templates'); $twig = new Twig_Environment($loader, array( 'cache' => 'cache', )); // Add twig extension. $twig->addExtension(new \Twig_Extensions_Extension_Array()); return $twig; }; With this setting, Twig always

问题 I want all read & write requests to a PCIe device to be cached by CPU caches. However, it does not work as I expected. These are my assumptions on write-back MMIO regions. Writes to the PCIe device happen only on cache write-back. The size of TLP payloads is cache block size (64B). However, captured TLPs do not follow my assumptions. Writes to the PCIe device happen on every write to the MMIO region. The size of TLP payloads is 1B. I write 8-byte of 0xff to the MMIO region with the following

问题 I want to set a far future Expires headers to reduce requests made from individual browsers. I'd also like to set Cache-Control: s-maxage=600 so that proxy caches (and CDNs) revalidate with the origin every 10 minutes for fresh content. Will browsers honour the Expires header despite the existence of a Cache-Control header (which supposedly supersedes it) with a s-maxage directive? 回答1: If a response includes both an Expires and a Cache-Control max-age directive, the max-age overrides the

问题 Problem: When caching an instance of a class and immediately getting it back out of cache, i get the object back (its not null), but all of its properties / fields are null or defaults. _cacheHelper.PutInCache("testModuleControlInfoOne", mci); //mci has populated fields var mciFromCacheOne = _cacheHelper.GetFromCache("testModuleControlInfoOne"); //mciFromCacheOne now has null or default fields So I suspect the way the object is structured is the problem and AppFabric is not serializing the

问题 I am trying to sort out a friends service. Basically it gets into error as soon as I start it in constructor. Here are the code fragments. public class DefaultCacheManager : ICacheManager { private readonly Microsoft.Practices.EnterpriseLibrary.Caching.ICacheManager _cacheManager; public DefaultCacheManager() { //Code blows here _cacheManager = CacheFactory.GetCacheManager(); } The error I get is below. Unhandled Exception: System.TypeInitializationException: The type initializer for 'Test

问题 Regarding my previous Question, Why do == comparisons with Integer.valueOf(String) give different results for 127 and 128? , we know that Integer class has a cache which stores values between -128 and 127 . Just wondering, why between -128 and 127 ? Integer.valueOf() documentation stated that it " caching frequently requested values " . But does values between -128 and 127 are frequently requested for real? I thought frequently requested values are very subjective. Is there any possible
