For a mock web service I wrote a little Django app, that serves as a web API, which my android application queries. When I make requests tp the API, I am also able to hand over an offset and limit to only have the really necessary data transmitted. Anyway, I ran into the problem, that Django gives me different results for the same query ...
Background: I've implemented a stochastic algorithm that requires random ordering for best convergence. Doing so obviously destroys memory locality, however. I've found that by prefetching the next iteration's data, the performance drop is minimized. I can prefetch n cache lines using _mm_prefetch in a simple, mostly OS+compiler-porta...

My goal is to cache all the images, css and js to improve the performance while online browsing, i'm not planning on offline browsing.

I have a page that makes the same JSONP request multiple times in a single page load. In most browsers this works fine, but Safari caches the response locally until such time as the page is reloaded. Even when I send back a Cache-Control: no-cache header on the response. consider the following example code: var plcbCnt = 0; var plcb ...
My bookmarks.html file is 40 MB in size. Anytime I edit a bookmark in Bookmark Manager (Firefox), I find myself waiting 10-20 seconds for the operation to complete. (Looking at the Activity Monitor, I can see there is a lot of disk activity). Q: How can I tell my OS to specifically cache the file "bookmarks.html" (so that read/write o...

GET /normal/html/page?ajax=true X-ajax: true What I've setup in my controller is: before_filter do |controller| if request_by_ajax? ApplicationController.layout false end end ...
I was profiling the performance of my web application using Google's Page Speed plugin for Firebug and one of the things it says is that I should 'leverage caching' — "The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources". When I dug deeper I ...
Hey, So as in the title, my stylesheets keep on caching for no apparent reason. It is only today I have started testing my VB.Net website in IE8 and using jQuery on the customer front end, and it is only the past 30 - 45 minutes that I have noticed this happening. There was one background-color which I changed a few minutes ago with no...
I'm trying to set up memcached on a django project on which I'm using the i18n internationalization system. Sadly, it looks that memcached is not caching different versions of the same page according to the language. In facts, when I switch language, it gets the previous cached page, without caring about the language switch. I'm using...
Is there an application or a code I can use to check which cache functions are turned on? On this app I'm working on, I thought there was mysql cacheing, but since I started using the SELECT SQL_NO_CACHE in one of my queries (applied yesterday), the cacheing has not stopped. This leads me to assume it's a php cache function that's occ...
Is there a way to globally trap MemoryError exceptions so that a library can clear out caches instead of letting a MemoryError be seen by user code? I'm developing a memory caching library in Python that stores very large objects, to the point where it's common for users to want to use all available RAM to simplify their scripts and/or ...
I'm using the following attribute on a web method in a web service: [WebMethod(CacheDuration = 60)] Is it possible to make the CacheDuration value of 60 configurable from a web.config setting? Or is there another was to set CacheDuration not using an attribute? ...

I am considering caching an entire web page locally on the iphone, i.e. I want to provide a url and have the device download all the assets automatically. ASIHTTPRequest offers a cache, but as far as I understand it will only cache whatever url you feed it. I wonder if anyone has implemented a caching mechanism that will parse the downl...

Hi All, We have a requirement to cache web pages as accurately as possible, so that we can go back and view a version of a page at any previous point in time. We'd like to be able to view the page as it really was - with the right css, javascript, images etc. Are there any OS libraries (any language) that will fetch a page, download al...
What is the best way of caching things in GWT. Data retrieved from RPC calls. I am interested in Data Structures and frameworks available out there, like ehcache. I am using gxt and have been storing things in the FastMap. What is the load capacity for the FastMap, is this the best way to do things. I know it eventually compiles to jav...
