This one has me stumped. I have a view with a cached fragment: - cache :key=>"news" do %h2 News - etc I have a sweeper that uses: def expire_home_cache puts "expire_home_cache" expire_fragment(:key => "news") end The sweeper is called as I can see "expire_home_cache" in the console output. But the fragment is not...
I have a Cocoa app containing a WebView. I'm targeting the 10.4 SDK due to the app's installed customer base. (i.e. I cannot require Leopard.) I have two files: index.html and data.js. At runtime, in response to user input, I write over the data.js file, often, populating it with current data from the app. (The data.js file is used b...
I'm trying to eliminate startup lag when playing a (very short -- less than 2 seconds) audio file via AVAudioPlayer on the iPhone. First, the code: NSString *audioFile = [NSString stringWithFormat:@"%@/%@.caf", [[NSBundle mainBundle] resourcePath], @"audiofile"]; NSData *audioData = [NSData dataWithContentsOfMappedFile:audioFile]; NSE...
In the Java Control Panel on Windows there are settings for "temporary internet files" wherein all the applets and webstart stuff is cached. For certain users of our application this caching doesn't work properly and they need to delete all the files through the control panel before our webstart application will update itself properly. ...
We are considering using ehcache (1.6.0-beta5) to enable second level caching of a number of tables which are never modified. We have set up a read-only ehcache region for this table and currently it seems to be working fine. The Hibnerate POJOs stored in the cache are all immutable. One of the developers here raised an issue that the...
I am wondering how to verify that Hibernate's L2 cache performs correctly. I have an application running on a cluster of JBoss 5 instances with JBoss Cache. Load testing would answer the question of performance. But how to make sure that cluster related issues like the cache invalidation between nodes works like it should be? ...
Has anyone tried to store Lucene index in JBoss Cache? Are there any good implementations of Lucene Directory for it? I found sources only for this one but I can't find any documentation or testimonials on it. Basically what I would like to do is to store Lucene index in JBoss Cache and manipulate it with application written with GridGa...
The following FreeTextTable query takes > 10 seconds on the first request, but about a second for subsequent requests: SELECT [Key], [Rank] INTO #matches FROM FREETEXTTABLE(Book, [Description], @searchWord) After approx. 10 minutes of inactivity the next request will once again take > 10 seconds. This seems like the freetext cache is ...

I need to clear all APC cache entries when I deploy a new version of the site. APC.php has a button for clearing all opcode caches, but I don't see buttons for clearing all User Entries, or all System Entries, or all Per-Directory Entries. Is it possible to clear all cache entries via the command-line, or some other way? ...
for a large project ive worked on (~310k uniq/day, large site, lots of templates, lots of content), we have to deal with the client selling several sections of the site (each with different layouts) for ad revenue. sometimes, its the top of the page for a 900x250, sometimes its a 952x200 under the nav, sometimes it requires a new div wit...
I am trying to determine which implementation of the data structure would be best for the web application. Basically, I will maintain one set of "State" class for each unique user, and the State will be cached for some time when the user login, and after the non-sliding period, the state is saved to the db. So in order to balance the db ...
I'm after a definitive reference to what ASP.NET code is required to disabled browsers from caching the page. There are many ways to affect the HTTP headers and meta tags and I get the impression different settings are required to get different browsers to behave correctly. It would be really great to get a reference bit of code commente...
need to add a 2nd css stylesheet to a page. do i add a 2nd link line and load it by url, or add a @import to the original? what is worse for page load times? what is worse for server load? what is better for client side caching? what is better/more accepted 'in general'? (note: assume no cdn or memcache, just a normal regular average...
I have a few classes which have a property which is unique to that object, for example for the User class the property Username should never be duplicated. NHibernate doesn't seem to support loading of an object by unique key which is then cached in the same way that Load() or Get() does. Am I correct when I say that? If I am then I wi...
I have an application that was written in vanilla ASP.NET that I would like to port over to ASP.NET MVC. I, however, am confused about the right place to persist objects. I need to persist for a couple reasons: I would like all to have a single database connection, wrapped in a "repository" or "manager" style object. Each user has a ...
I'm using JPA and I am using second-level cache for all the reference entities. Everything's working well, I can get the entities from second-level cache is they were already been selected before. Now, I have two applications, they both use the same database (so they both use the same table, values, etc). 1.The read-only application ju...
Hi, background: I work on an asp.net web application that is on a company intranet. cookieless="true" is set in the web.config in the sessions configuration. The application is launched off a page and can run in several different modes (a different link for each mode). It is a business requirement that multiple instances of the applicat...
So I'm trying to introduce some caching into my Asp.Net application. New data for the user is returned from the DB in the form of large datasets. Whenever a user requests data I insert this dataset into the HttpRunTime.Cache. At the moment I'm setting their caching time to 2-3 hours. And these are really large datasets and I put them in ...
Is there a built-in asp.net way to conditionally serve pages, for example I want the following logic: If there is a session data I generate a page, if there is no session data I serve the cached page. I am only interested in knowing about a built-in asp.net mechanism for this. If it does not exist I am probably going to simply ...
