caching

问题 I need to iterate through my server's cache, which is a LocMemCache object, and remove every key in the cache that begins with the string 'rl:' . From what I understand, the only functions that the caching API django provides are get, set, and delete. Here is a rough example of what I am trying to do: def clear_ratelimit_cache(): if any('rl:' in s for s in cache.get(s)): log.info( 'FOUND SOMETHING') cache.delete(*something else here*) Trying to do this, however, gives me a NameError , stating

问题 Im using new setting to increase item size in memcached, but i cant store something larger than 1mb through Django backend. I know that memcache module require some setting to achieve thath, and Django use this module in backend. 回答1: From Maximum size of object that can be saved in memcached with memcache.py: There are two entries about that in the memcached FAQ : What is the maximum data size you can store? Why are items limited to 1 megabyte in size? The answer to the first one is (quoting

问题 I am newbie to CI cache. I am facing some weird problem with codeigniter page caching. $this->output->cache(300); I was expecting that cached version would not load if arguments in GET[] would change. But it is loading cache without considering any GET[] parameters. I have one page where it says whether comment has been saved or not [via get parameter], /product/product-name/?saved=true redirecting to same page where comment form is located. But it is not working. How can i invalidate old

问题 I am working on a "smart" caching system that uses pdo and memcache. However, I am stuck at this error. Can you help me out? My Code: $session = "a121fd4ztr6"; cache_query("SELECT * FROM `session` WHERE `session` = :session: LIMIT 1;", array(':session:' => $session)); // CACHE QUERY function cache_query($sql, $params) { global $db; global $memcache; $name = 'querycache-'.md5(serialize(array($sql, $params))); $result = $memcache->get($name); if (!$result) { if(!($db)){ require("db.php"); }

问题 I know this exception is caused by some properties being defined as virtual and therefore it's trying to load them lazily after the context has been disposed. However, I don't want to load the entire object graph just to perform a fairly simple query. And if I try to cache the objects when the context is still alive, it tries to lazily load everything, and slows it down considerably . Is there any way of performing the query, and then getting a disconnected result set, so that it doesn't try

问题 I've got a problem after adding HTML5 caching to a singlepage app written in backbone on rails. Browser (chrome) isn't reloading the html and this causes problems in 2 ways: 1) The skeleton html for backbone sometimes changes - at very least to let backbone know that user is signed in. However with html not being loaded, the app doesn't know that (after refresh for example). I could query the server on page load, but that's another request which I hopped to avoid. Also this would force moving

问题 I am a beginner for Ignite, so I have some puzzles, one of which is as follows:when I try to query cache, whether it can look if memory contains or not. If not, then whether it will query database? If not,how to achieve such way? Please help me if you know.Thx. 回答1: Queries work over in-memory data only. You can either use key access (operations like get() , getAll() , etc.) and utilize automatic read-through from the persistence store, or manually preload the data before running queries. For

问题 When I turn on output caching for my service it doesn't appear to be cache-worthy in IIS. It really should be since I'm returning the same JSON content over and over. The varyByQueryString option seems like it would do the trick, but since my resources are URI based, there really isn't a query string, just a path to a resource. Has anyone successfully gotten IIS to output cache a WCF REST service? 回答1: After much digging using the FREB logs in IIS, my service is in fact cache-worthy. You can
