Is it possible to cache the response of a http handler on the server and on the client? This doesn't seem to be doing the trick: _context.Response.Cache.SetCacheability(HttpCacheability.Public); _context.Response.Cache.SetExpires(DateTime.Now.AddDays(7)); The _context is the HTTPContext passed as an argument to the ProcessRequest met...
We have a small web farm(2 servers) balanced by the built in network load balancer in Windows 2003. We have a few pages that use page caching. My question is: Is it possible that that a given user could cause a page to be cached and another user see that content? Here is the page directive for the page in question: <%@ OutputCache D...
I'm doing an iPhone version of a desktop site that includes a blog. The blog often embeds images from other domains (the image URLs always start with http:// in this case, obviously), but because I'm using cache-manifest, these images don't load because they aren't declared in the manifest file. I have a NETWORK: whitelist section that ...
I've been doing web development for a while and have yet to read a good answer to this question: Given a page that executes transactions through a postback, how do you prevent the user from duplicating the transaction when they do something as simple as hit the back button? I've explored trying expire the cache but I must admit I'm l...
My iPhone app embeds a UIWebView which loads html via a custom NSProtocol handler I have registered. My problem is that resources referenced in the returned html, which are also loaded via my custom protocol handler, are cached and never reloaded. In particular, my stylesheet is cached: <link rel="stylesheet" type="text/css" hre...
I’m relatively new to testing and MVC and came across a sticking point today. I’m attempting to test an action method that has a dependency on HttpContext.Current.Cache and wanted to know the best practice for achieving the “low coupling” to allow for easy testing. Here's what I've got so far... public class CacheHandler : ICacheHan...
I generate output with php. I've been reading about caching HTML elements (e.g. images, text) in the browser so that these don't have to be reloaded. However, I haven't found the right directions on how to get it done. It's like "simply cache the elements you want and you're done!" - great, but how do I cache something like this: <div ...
Hi, I have enabled caching in IIS 6 for all our static images and CSS(by right clicking on those folders in IIS and enabled Content Expiration after 30 days under HTTP Headers). When I run Google PageSpeed, and look at the resources tab, the status of those images and css shows up as 200, but I was expecting a 304(not modified). When...
The company I work for is looking to implement a caching solution. We have several WCF Web Services hosted and we need to cache certain values that can be persisted and fetched regardless of a client's session to a service. I am looking at the following technologies: Caching Application Block 4.1 WCF TCP Service using HttpRuntime Cachi...
I de-normalized my database, since the application was crawling otherwise, and Im storing a list of categories for each item in the DB as a raw html version, and simply echoing it out in my design. Each category is actually a link, which is include a tag. Naturally, this is abit of a pain, especially if I want to change the look of how...
I have heard of .NET APIs for memcached. Is there any equivalent for EHCache? I am envisioning a cluster of linux machines running EHCache, serving cached objects for a farm of ASP.NET webservers. Is this practical? Can this be done without installing Java on the ASP.NET servers? ...
In my web application, my users have many events. One such event is "user updated facebook status." A user could have hundreds of that type of event, and there are 10 types of events. I need to display event counts and other user statistics based on events in a very scalable manner. This is because each user will be able to see his o...
I am checking out the OutputCacheProvider in ASP.NET 4.0 and using it to store my output cache into the MongoDb database. I am not able to understand the purpose of Add method which is one of the override methods for OutputCacheProvider. The Add method is invoked when you have VaryByParam set to something. So, if I have VaryByParam = "id...
Normally i have a static class that reads and writes to HttpContext.Current.Cache However since adding threading to my project, the threads all get null reference exceptions when trying to retrieve this object. Is there any other way i can access it, workarounds or another cache i can use? ...
I'd like to work with a dict in python, but limit the number of key/value pairs to X. In other words, if the dict is currently storing X key/value pairs and I perform an insertion, I would like one of the existing pairs to be dropped. It would be nice if it was the least recently inserted/accesses key but that's not completely necessary....
I'm have an action /json that returns json from the server. Unfortunately in IE, the browser likes to cache this json. How can I make it so that this action doesn't cache? ...
I'd like to use use maps in my application, so that there will be as less as possible traffic. Perfect solution would be caching of map slices. I know it's not possible with google maps (license). I took a look on OpenStreetMaps and it seems as good solution. The next: SDK. The only one I've found is from CloudMade. The problem is, I fou...
Hi all, I am a newcomer to hibernate. It would be great if someone could comment over the following query that i have: Say i have a parent class and each parent has multiple children. So the mapping file of parent class would be something like: parent.hbm.xml <hibernate-mapping > <class name="org.demo.parent" table="parent" lazy="tru...
Hi guys! Tried to make a little old school ajax (iframe-javascript) script. A bit of mootools is used for DOM navigation Description: HTML: 1 iframe called "buffer" 1 div called "display" JAVASCRIPT: (short: copy iframe content into a div on the page) 1) onLoad on iframe triggers handler(), a counter makes sure it only run once (th...
Hello. I am working for an intranet application. Therefore I have some control on the client machines. The JavaScript library I am using is somewhat big in size. I would like to pre-install OR pre-load OR cache the JavaScript library on each machine (each browser as well) so that it does not travel for each request. I know that browsers ...
