I have an ASP.Net website on IIS7 and I am planing to increase the MaxProcesses to match the number of cores on the server (4 cores, 64bit Windows Server 2008). From what I read, if I increase the MaxProcesses to create a web garden I have to set an out-of-process state server, so I am planing to use the ASPState service to share sessio...
hi.. im doing my final project and its about optimizing web performance (focus on caching). i plan to use eaccelearator as a tool in my final project. i need to know the background process of it, the flow diagram about how it works and how an opcode cache can boost performance of websites. it can be eaccelerator, or anykind of opcode cac...
Hi! It seems to me that JBoss reuses entity managers and the underlying hibernate sessions for multiple requests. I have run a test which proves that in some cases the state of an entity may be out-dated even if it is just fetched using em.find(). How can I disable this behaviour and force to clear or throw away used sessions to ensur...
Hey guys, I have a UIImage that I'm instantiating using imageWithData: (the data is loaded from the bundle using [NSData dataWithContentsOfFile:]). I'm then drawing the image like so: NSData *imageData = [NSData dataWithContentsOfFile:fileLocation]; UIImage *myImage = [UIImage imageWithData:imageData]; //These lines are superfluous ...
Does a JavaFX applet use the browser's cache or any cache when downloading files over http://? I know it will cache the .jar files that define the application. I want to write an audio player that caches the media it downloads. ...
Not sure if this makes sense, but why did adding the code on my http handler (responds to a ajax request returning a json result): adding context.Response.Headers.Add("Cache-Control", "no-cache"); cause an error and say integrated pipeline mode has to be set? ...
I'm having a peculiar problem: PHP SCRIPT: // checks If-Modified-Since header (if nothing has changed) // Sends HTTP/1.0 304 Not Modified // Sends Cache-control: public, must-revalidate // exits // if NO If-Modified-Since or something has changed // builds content // Sends Last-Modified: [DATE TIME] // Sends Cache-control: public, mus...
As I understand it, using a hypertext-driven RESTful Web service, a client is not supposed to know anything about server URI layout except for a couple of well-known entry points. This is supposed to enable the server to control its own URI space and reduce coupling with the client. When a client for the service sends a successful reque...
I'm using a Substitution control in my master page, and I want to render a user control content (related to the login area of my website) in the Substitution . Seems like I must have a reference for the requested page so that it could render the control. But I need to render the control in the master page itself, as it's shared across mu...
I need the client (using javascript) to invalidate a page it has and essentially fetch a new version? I thought I could do it all with headers: http://stackoverflow.com/questions/1295397/invalidating-cached-content-if-modified-headers If there NO way to have the browser refresh its current cached version, with out making a new request ...
Good aftenoon, I created a super simple console app to test out the Enterprise Library Caching Application Block, and the behavior is blaffling. I'm hoping I screwed something that's easy to fix in the setup. Have each item expire after 5 seconds for testing purposes. Basic setup -- "every second pick a number between 0 and 2. if th...
Hello guys, I'm studying high-performance coding for websites in PHP, and this idea popped into my mind: We know that accessing a database uses a significant amount of CPU usage, so we cache such data, saving it to the HDD. But I was wondering, can't it rest in the RAM of the server, so I can access it even more faster? ...
I'm using a Smarty template for my web application Registration / Sign-up form. The form is slow to load, can I cache the registration form in order to speed up the loading of the page? On the form page, I use SESSION and do lots of PHP error checking to ensure that the form fields are completely & correctly inputted. If not, I redis...
How do I cache everything on a Smarty template page except for a small portion of the content (which is truly dynamic)? ...
I have been pondering for a while how to best cache IQueryables. I am using a repository pattern to fetch data into a class such as this one: public class Item { public int Id { get; set; } public string Name { get; set; } public IQueryable<Category> { get; set; } // For simplicity. It is actually a LazyList<Category> contai...
I am building a web-store with many departments and categories. They are stored in our database and accessed often. We are using URL rewriting so almost every request within the store generates a lookup. We also need to iterate over the data frequently to generate menus for the main store and the department pages. This information wil...
We have a java application deployed in a local LAN, which is cached in JRE cache folder. By default this cache space can be up to 1GB in size and in most cases here all computers have used that space in total. This will not be an issue if there is no need for doing daily backups of all user's home folders in LAN (and there are more tha...
How is it possible to create various cached versions of a user control based on a field within the control. So for example I have a user control that has the following declaration: int someInt = 0; Let's say this variable could be set to any value between 1 and 10. If I want a separate cached user control for each value of the variabl...
I have a weird situation with my sharepoint css. It is deployed as part of a .wsp solution and up until now everything has been fine. The farm it deploys too has a couple of webfront ends and a single apps server and SQL box. The symptom is that if I deploy the solution, then use a webbrowser to view the page it has no styles, and if ...
I've written an application for Google AppEngine, and I'd like to make use of the memcache API to cut down on per-request CPU time. I've profiled the application and found that a large chunk of the CPU time is in template rendering and API calls to the datastore, and after chatting with a co-worker I jumped (perhaps a bit early?) to the ...
