Client side caching using Last-Modified header and OutputCacheAttribute in asp.net mvc 3

由 风流意气都作罢 提交于 2020-01-01 12:13:10
问题 Edited I want to cache images on the client and know that there are different ways to do it in mvc 3: (correct me if I'm wrong) 1) You can use OutputCacheAttribute which works with the help of Expires http header. But it will return 304 Not Modified unless the time expire (even if the image was changed). 2) To avoid displaing stale images You can use Last-Modified http header (with OutputCacheAttribute ). In this case the browser sends the request to the server with If-Modified-Since http

Best practice when using Azure AppFabric Caching Service?

由 一个人想着一个人 提交于 2020-01-01 12:10:39
问题 I have successfully started using Azure AppFabric Caching Service, but I' not sure what the best practice way of creating the DataCacheFactory object is. Now I'm creating it for every call into the cache, but apparently this is not the ideal way of doing it... Some advise call for a Singleton. But I'm not sure I understand how this would be implemented (not the actual Singleton class, but how to tie it all together). Today I have a CacheProvider class that is created for me using Ninject

问题 What would be the programmatic steps written in "C" associated with clearing the L2 cache on a Linux OS machine? /sys/devices/system/cpu/cpu0/cache/index2/size = 6144K x 8CPUs 回答1: The closest you can get in any remotely clean/portable way: char dummy[L2_CACHE_SIZE]; memset(dummy, 0, sizeof dummy); Depending on your CPU, there may be privileged opcodes that can clear the cache, but I don't know anything about them or how you might access them. It's likely that if they exist, you still might

Browser Cache issues in Laravel 4 Application

由 南楼画角 提交于 2020-01-01 10:53:12
问题 I'm having an issue with the browser cache interfering with my Laravel application. If the browser cache is disabled, everything works fine. However, if enabled, and the same link is clicked repeatedly, the Laravel method to create the view or collect data is not even executed. The implications are manifold. For instance, a form to edit a resource or a grid which displays data (loaded form the server using ajax), do not show the current values until the browser is reloaded. I've put a line in

how to build a in-memory server side cache in php?

由 冷暖自知 提交于 2020-01-01 10:48:12
问题 I am trying to reduce the amount of database access by providing a in memory cache. I understand that I can get a cache by using session and cookies, however this only works on a per client basis. if the same query is made once in every session, then the cache will be useless. But I only want to access the database once and have it cached. Is there a way to make create a cache in memory that can be accessed by the server side script? I don't want to store the cache data in a file .. 回答1: You

Storing C/C++ variables in processor cache instead of system memory

由 痞子三分冷 提交于 2020-01-01 10:11:08
问题 On the Intel x86 platform running Linux, in C/C++, how can I tell the OS and the hardware to store a value (such as a uint32) in L1/L2 cache, and not in system memory? For example, let's say either for security or performance reasons, I don't want to store a 32-bit key (a 32-bit unsigned int) in DRAM, and instead I would like to store it only in the processor's cache. How can I do this? I'm using Fedora 16 (Linux 3.1 and gcc 4.6.2) on an Intel Xeon processor. Many thanks in advance for your
