I'm a little overwhelmed reading through the ehcache user guide http://ehcache.org/EhcacheUserGuide.html#id.s20. I'm trying to figure out how to set up a simple ehcache app that has a distributed cache. I'd like to just run the app multiple times and have it share the cache between the multiple instances. Is there an example app I can j...
For Internet caching, an update heuristic is to hold the document for a time that is proportional to the known lifetime of the object. If we follow a typical 60% rule, and we receive a response as follows: HTTP/1.0 200 OK Date: Tue, 23 Jun 2009 09:23:24 Server: Apache/1.3.0 (Unix) Last-Modified: Mon, 8 Jun 2009 09:23:24 Content-Type: te...
Caching can be used to reduce the access overhead. Hierarchical caching takes the advantage of the topology of the Internet and deploys the cache at different ISPs. Suppose the hierarchical topology of the Internet is composed of three-level ISPs, national, regional and local. The hit ratios of searching a webpage at different level of t...
I'm writing a web service for my application and want to know the best way to handle the possibly tons of requests I might get. A lot of the data probably won't change throughout the day but the particular script I'm writing makes 3 MySQL queries which seem a little excessive considering the data will probably be the same as the last re...
Referring to nsICacheService (https://developer.mozilla.org/en/NsICacheService) and nsICacheVisitor (https://developer.mozilla.org/en/nsICacheVisitor): Where do I get an instance of nsICacheVisitor? Where do I get a list of devices so that I can call visitEntry() and visitDevice()? ...

Now i want to know what is the best method to do this. Do i need to fetch all these data in the application on start...
Hi. I have a simple program that first writes some native x86 instructions into a declared buffer, and then sets a function pointer to this buffer and makes a call. I'm noticing a severe performance penalty, however, when that buffer is allocated on the stack (as opposed to on the heap, or even in the globals data area). I verified th...
I have an automatic slideshow on the main page of some site. Images are rotating every 10 seconds, but when they appear for the first time they aren't already loadead (I guess), so a blank is show. I think that preloading these images they will show fine, but I don't know how to preload them. I use the following code to preload all the ...
I'm porting application from custom authentication system to cake's Auth. Everything works fine for logged user (even with smaller privileges), but doesn't for non logged users (who are most users of site). I'm managing privileges for them with $this->Auth->allow() in FooController::beforeFilter (but not with AppController::beforeFilter)...
I have a static Cache that at a set time updates a generic list of Objects from a database. It is just a simple static List: private static List _myObject; public List<myObject> FillMyObject() { if(_myObject == null || myTimer) _myObject = getfromDataBase(); } I have 2 methods to update my object called UpdateMyObject an...
Hi Friends, I'm using the WebBrowser control inside a Windows Form to display a PDF. Whenever the PDF is regenerated, however, the WebBrowser control only displays its local cached version and not the updated version from the server. I'm using the Refresh() method shown below to try and force the control to reload the PDF, but it does...
I've got a WCF service with the following settings: NetNamedPipeBinding ConcurrencyMode.Multiple InstanceContextMode.Single Now I've got a client that accesses to this WCF service in a multi-threaded fashion. As far as I understand I have to open a new connection to the service for each thread to avoid threads to block each others. ...
It would be extremely useful for web development. ...
Greetings, I am writing a networked flash application. The server (an independent C++ app) sends resources for the flash client to manipulate and/or display, eg, images and sound. I'm assuming that the browser stores these resources in its cache. Since the resources can be pretty big, I don't want to resend them from the server each ...
Hi stackoverflow experts I've been experimenting with the audio and local storage features of html5 of late and have run into something that has me stumped. I'd like to be able to cache or store the source of the audio element locally to enable speedier and offline playback. The problem is I can't see how this is possible with the cur...
I added the following annotation to enable cache to one of my EJB3 entities, to test caching with ehCache, where I use Hibernate as the persistence provider: .... import org.hibernate.annotations.Cache; import org.hibernate.annotations.CacheConcurrencyStrategy; @Entity @Table(name = "F") @Cache(usage=CacheConcurrencyStrategy.READ_WRITE...
We are in the process of rewriting some of our websites and trying to make the most use of browser caching for our users. We have created a group of shared css files that we plan to use as a "corporate branding" across multiple sites that we've created. The reason for this, we know that browsers will cache a CSS file for a determined le...
Currently browsers have incomplete caching implementation. It only allows to set expiration or keep immediate expiration. Important 3rd option to expire cache programmatically is missing. Without that 3rd option developers cannot deploy new version of code efficiently and reliably. If they use 2nd option it is inefficient if they have ...
I'm rendering polymorphic records in a view by looping over the polymorphic records and choosing the appropriate partial to use for the polymorphic relationship. However when a user is administering the site each polymorphic record may (or may not) have a second (alternate) partial that should be used in that situation. So currently I'...
I'm trying to do some simple locally-hosted development using the Ext framework. The site is configured as a virtual directory under IIS 7, so that http://localhost/app points to the index file. The path works fine; the file loads. Here's my problem: despite the fact that I am not making any changes to the very sizable Ext library javas...
