I am using Single-Table Inheritance (STI) on one of my models for a Rails App and I am having problems storing model objects on a constant. I have isolated the problem into a sample project and submitted it to GitHub: http://github.com/fcoury/rails-sti-caching What I am trying to do is loading a model instance (in this case a Music mode...
What would be some advantages of using etags/stale?/fresh_when? instead of page caching (on a file cache)? Apache automatically handles etags for static files, but even if it didn't, page caching would still be better since the Rails app doesn't even get called. So, in what instances would I use the methods provided by Rails (stale?/fr...
I'm thinking about using the java application object to implement a simple cache, to save a few configuration variables, and a couple of xml with often used info... I'd like to know where is the application data phisically stored (a system file, in memory, db), how can it be configured, and if there's any kind of limitation, like space,...
I wonder, does there exist something like Velocity, but for internal use? Essentially a .net Object Cache that I'll install at a server and that speaks WCF (or something more appropriate?) with my applications - mainly ASP.net, but possibly WinForms as well. Objects should be persistable if possible, but held in memory most of the time...

Details We have an ASP.Net application that uses several webservices. One of the webservice methods can take a long time to run. To address this we use cachi...

I have started having problems with my VPS in the way that it would faill to serve the pages on all the websites. It just showed a blank page, or offered to download the php file ( luckily the code was not in the download file :) ).

I'm creating a Silverlight front end for an existing desktop app written using CSLA. One thing that I'm having trouble with is converting classes like the following: public class SomeCollection : Csla.ReadOnlyListBase<SomeCollection, SomeObject> { private static SomeCollection _list = null; public static SomeCollection GetSomeCo...
Hi, I was wondering whenever exists a solution to perform synchronization in JavaScript code. For example I have the following case: I'm trying to cache some response values from AJAX call, the problem is, that it's possible to perform simultaneously several calls, therefore it leads to race condition in the code. So I'm very curious to ...
The web application I'm working on serves up images with URLs like /image?name=a.gif. Pages are loading slowly partly because browsers are not caching the images. Is there any combination of http headers that will persuade IE to cache the images even though the URL has a query string in it? I'm trying to avoid the browser making any unn...

On the clien...

I needed to find a way that two applications can use the same cache, and after some quick research it seems that we will need a distributed cache to achieve this. Further Googling turns up a number of solutions, NCache, SharedCache, Velocity, memcached. This cache will be used for caching webpages in a Microsoft Enviroment using Asp.Ne...
If my computer is the web server for multiple live websites, is there any harm if i type ipconfig/dnsflush in my command prompt editor?? I always got this problem.
