Most examples use time-based cache expiration. I'd like to read more about file caches (where the database is called only when there is no file in a given directory). This is for a basic information site with CMS functions made with php/mysql. My searches are returning too many sites on web applications. Adding CMS to the search returns ...

I'm setting up a caching system in PHP for database queries. So when a query like "SELECT * FROM table" is called, it either returns the cached results of that query or the results directly from the DB. $query = "SELECT * FROM table"; [...] $data = mysql_query($query); [...] fwrite($file,json_encode($data)); [...] The problem is I'm ...
Hi, I want to ensure that my servet's response is never cached by the broswer, such that even if two identical requests are made (a nanosecond apart), the server is always contacted. Is this the correct way to achieve this: class MyServlet extends HttpServlet { protected void doGet(HttpServletRequest request, HttpServletResponse r...

Hi everybody, I've a question regarding SqlCacheDependency configuration. Every resource I've read requires the developer to define the polled databases into web.config. This is not a good scenario for our application that connects to different databases, because we don't want to edit web.config each time we add / remove a database. We ...
I am building a Ruby on Rails application where I need to be able to consume a REST API to fetch some data in (Atom) feed format. The REST API has a limit to number of calls made per second as well as per day. And considering the amount of traffic my application may have, I would easily be exceeding the limit. The solution to that would...
Does anyone know how to instruct rails to NOT cache classes that are included within the lib folder? ...
I have been googling for hours and trying to figure this out, and I just can't. I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com"), it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly appa...
I'm experiencing a rather bizarre behaviour in JQuery. I'm dynamically loading a series of scripts using this code: for (var i=0; i<requiredScripts.length; i++) { $.ajax({ url: baseURL+"js/"+requiredScripts[i], async: false, dataType: 'script', success: checkLoaded }); } The checkLo...
I have a page where once a button is clicked, it is replaced by an Ajax spinner whilst the user waits for the next page to load. I am controlling (or attempting to control) caching using .htaccess. If the user hits back (browser button, mouse button, alt+left, backspace) it needs to reload the page from the cache. IEs 6-8 and Chrome wer...
I'm pretty new to caching strategies and implementations. I'm working on a project that will be database intensive, but also have information being updated and changed very regularly. I've found enough info to know generally how to develop the caching function, but what I'm unsure about is the general strategy. If I cache all query r...
i have read a few different things, it sounds like output cache will not cache a different copy of results for each user. so if user A has 3 menus and user B only has access to 1 of them, then caching the view result would show all 3? how can i cache things for each user so that it's not shared? thanks! ...
We make changes often on our website (which uses caching) and sometimes user don't know to refresh a page in order to get the newest copy of it. If we do update a page, how can we force the users browser to know that there is a new server version, and to use that rather than their browsers cached page? ...
i have seen a few (discouraging) questions related to this subject but I am still not clear on the answer. is it possible to cache video content for immediate playback in an offline web app on the iphone or ipad? (i believe that there is a 5mb limit for any cached file.) can videos cache the same way other files can, using the manife...
Hello, I've been wondering: is it possible to shield a directory/file on a server from the outside world, but make it accessible to PHP? It's fairly simple. I'm caching webpages on my server with PHP in a certain directory, but I do not want web users to view these files or this directory directly. PHP, on the other hand, must be able ...
I'm using HttpClient for testing and when I have been restarting/redeploying to Tomcat I have been getting some sort of client side caching... For example I tried deleting my authentication servlet and ran my tester class (which connects using HttpClient) and I get the same response over and over. I'm going crazy trying to figure out wha...
I have a Django app, which populates content from a text file, and populates them using the initial option in a standard form. The file gets updated on the server, but when the form gets refreshed, it picks up content from the a previously saved version, or the version before the Apache WebServer was reloaded. This means that the file i...
EHCache allows for persistance of the cache, and it requires all objects that are being cached to be Serializable. The objects that are being serialized and written to the Disk are being written with ObjectOutputStream, which is fixed in its required fields and UID. link text My question is: Is there a way to force the serialization [...
Hi everyone, Interesting problem here - I'm making a small game using Flex 3 - now I have a static ImageAccess class, which first loads up all images and stores them in a static array for quicker access in the future. Now since I address the physical bitmapdata without calling Clone() (for efficiency issues) and once by accident I've wr...
