I pre-generate 20+ million gzipped html pages, store them on disk, and serve them with a web server. Now I need this data to be accessible by multiple web servers. Rsync-ing the files takes too long. NFS seems like it may take too long. I considered using a key/value store like Redis, but Redis only stores strings as values, and I susp...
We are working on a web application that is distributed across 3 load-balanced web servers. A lot of the data we retreive via NHibernate is stored in System.Web.Caching.Cache. System.Web.Caching.Cache does a lot to increase the responsiveness of an application, but there are a few issues that we don't exactly know how to resolve, such ...
I have a method whose output I'll be caching. It takes four parameters; string, string, int, and WindowsIdentity. I need to create a cache key based on those four parameters. Is it best to: Concatenate them all together as strings and use that key? var key = string.Concat(string1, string2, int1.ToString(), identity.ToString()); Or ...
Hello, I have just started to look at the caching block which sounds very promising but am having trouble getting it to work with a DataBackingStore. It works fine with a NullBackingStore but when I switch to data, I get the following error when trying to create the CacheManager from the CacheFactory: The type 'Microsoft.Practices...
I have long wondered what is more efficient with regards to making better use of CPU caches (which are known to benefit from locality of reference) - two loops each iterating over the same mathematical set of numbers, each with a different loop body, or having one loop that "concatenates" the two bodies into one, and thus accomplishes id...
Hi, I have EntityTypes generated from a database using Entity Framework 4. I would like to use Cache to store some of these EntityTypes for performance reasons. Is it safe to do the following provided that the object will be used for read-only actions: context.Students.MergeOption = MergeOption.NoTracking; var students = context.Student...
It's not clear to me from the descriptions of the cache manifest that I've read (e.g. http://www.w3.org/TR/offline-webapps/#offline and elsewhere) what this file does. I'll explain what I find to be unclear. The heading name ("Offline Web Applications") suggests that the cache manifest is relevant only for offline scenarios; the cache ...
Does DataNucleus support Cache Coordination? If yes, how can I enable and use it? I'm not actively using DataNucleus yet, but I want to consider it, if it supports Cache Coordination. Background: Cache coordination is used by multiple cache instances to inform each other about changed entities (e. g. via JMS or RMI). Its purpose is to ...
Hi, I have an application which I'm developing in GWT. I've noticed that sometimes (I'm not sure it happens all the time) after compiling, and generating a new version, if I will try to access my program's URL from IE8 it will result in a 404 in my eclipse log. I think this is because the browser caches the actual 1232dfsfda.html URL and...

Basically I have code as follows Repository Public Function GetRegions() As IQueryable(Of Region) Implements IRegionRepository.GetRegions ...

I'm thinking about adding another static server to a web app, so I'd have static1.domain.tld and static2.domain.tld. The point would be to use different domains in order to load static content faster ( more parallel connections at the same time ), but what 'troubles' me is "how to get user's browser to see static1.domain.tld/images/what...
I have a flex application about 2M need to send to browser, so I want the browser to reserve the file in cache forever unless I upgrade the version. I have set the ETAG and last-modified tag in http reponse header, but sometimes, when the user click the refresh, the swf file still be reloaded. So what http response header can I use to...
Hi guys, I'm trying to optimize my web application and unfortunately have ended up with a javascript file size of around 450K - that too after compressing [it would take a while for me to redo the javascripting but until then I have to go live] - I initially had made a number of small javascript libraries to work upon. And what I do is I...
Hi, I don't quite understand how Google Analytics cookies work with Varnish. Do pages that contain GA cookie not get cached? Do I need to remove the GA cooke in vcl_recv? If I do remove them, does that stop GA tracking visitors? ...

Hello everybody, So basically I've ran my site through ySlow and it has informed me that I should add Expires headers to some of the elements on my page to help with the caching. The page is mainly static content currently hosted on an Apache/2 server. If it helps at all the site is here. I'm not really sure how you alter the HTTP i...
