caching

Is it possible to cache a whole website including start html page and startup with no internet connection?

Our website is an AJAX website that makes no page requests after the initial start up of our website. Information is communicated with the server through XMLHttpRequests. Our website allows users to work online and offline without a connection during a user session. When a connection is detected our website "synchronizes" with the s...

Write-behind cache for .NET (free and simple) ?

I need simple and free write-behind cache for .NET. Does not have to be 100% reliable or fast. I have a growing website and I need something till Microsoft finally releases Velocity which should have write-behind in the near future. Do we have a simple write behind cache implementation for .NET? Do we have any .NET code samples on writ...

memcached expiration time

Hi, Memcached provides a cache expiration time option, which specifies how long objects are retained in the cache. Assuming all writes are through the cache I fail to understand why one would ever want to remove an object from the cache. In other words, if all write operations update the cache before the DB, then the cache can never con...

Sharepoint - how to enable caching w/o server access?

I am using WSS 3.0 in a hosted/shared (read: can make no server-side changes) environment. Unfortunately, between SP and IIS, almost nothing is getting cached, so page loads can be terribly slow.

cache in the browser -- tools and theory

My current tools include YSlow, Fiddler and the new PageSpeed. My questions is: is there a better tool for finding out exactly WHAT the browser is caching, WHEN it's caching it, and WHY other assets are not caching. A brain-dead simple explanation of HTTP headers, vis-a-vis caching would also be useful. The more gotchas the better, s...

Can anyone explain a best practice approach to implementing a cache buster in SASS? Meaning, on 'compilation' of my CSS, it appends a timestamp to images files. E.g., The following SASS code: !sprite="gubs.gif" ul li.selected :background :image= image_url(!sprite) :repeat no-repeat :position= "right" -222px S...

Java object caching, which is faster, reading from a file or from a remote machine?

I am at a point where I need to take the decision on what to do when caching of objects reaches the configured threshold. Should I store the objects in a indexed file (like provided by JCS) and read them from the file (file IO) when required or have the object stored in a distributed cache (network, serialization, deserialization) We a...

cache controller response

Hi, I'd like to use memcached to cache the response produced by my controllers. The controllers themselves are Grails controllers, but there's nothing really Grails-specific about the problem. If I could figure out how to solve this problem in a Spring MVC, Struts (or similar) application, I should easily be able to migrate the solution...

[Java] Cluster Shared Cache

I'm needing to fix a bug in an ASP.NET 2.0 app that uses ActiveReports 3.0 to generate reports from a SQL Server stored proc source.

What we're seeing is that ActiveReports is still displaying the early ve...
