cache-control

I am aiming to write an interceptor that add some headers in response. I currently have the following interceptor public class CachingInterceptor extends AbstractInterceptor{ @Override public String intercept(ActionInvocation ai) throws Exception { HttpServletResponse response = (HttpServletResponse) getActionContext(ai).get(StrutsStatics.HTTP_RESPONSE); if(null != response) { response.setHeader("Cache-control","no-store,no-cache"); response.setHeader("Pragma","no-cache"); response.setHeader("Expires","-1"); } return ai.invoke(); } } I need to enhance it in such a way that headers can be

How to clear cache in browser so a user could not view its profile if he is not login protected void ClearSession() { FormsAuthentication.SignOut(); Session.Clear(); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ExpiresAbsolute = DateTime.UtcNow.AddDays(-1d); Response.Expires = -1500; Response.CacheControl = "no-Cache"; } Patrick Hofman I think you are

okay, I'm still trying to get my head around some of the caching stuff and I have gone through a couple of examples I could find on Google. I have added the following code to my .htaccess file: ### activate mod_expires ExpiresActive On ### Expire .gif's 1 month from when they're accessed ExpiresByType image/gif "access plus 3 months" ExpiresByType image/png "access plus 3 months" ExpiresByType image/jpg "access plus 3 months" ExpiresByType text/javascript "access plus 3 months" Using the Chrome audit tools and the YSlow Firebug tool, it looks like this is caching some of my images/files, but

I am trying to get some html pages to be cached, the same way images are automatically cached via CloudFlare but I can't get CloudFlare to actually hits its cache for html. According to the documentation (Ref: https://support.cloudflare.com/hc/en-us/articles/202775670-How-Do-I-Tell-CloudFlare-What-to-Cache- ), it's possible to cache anything with a Cache-Control set to public with a max-age greater than 0. I've tried various combinations of headers on my origin Nginx server without success. From a simple Cache-Control: public, max-age=31536000 to more complex headers including s-maxage

On the Intel x86 platform running Linux, in C/C++, how can I tell the OS and the hardware to store a value (such as a uint32) in L1/L2 cache, and not in system memory? For example, let's say either for security or performance reasons, I don't want to store a 32-bit key (a 32-bit unsigned int) in DRAM, and instead I would like to store it only in the processor's cache. How can I do this? I'm using Fedora 16 (Linux 3.1 and gcc 4.6.2) on an Intel Xeon processor. Many thanks in advance for your help! There are no cpu instructions on x86 (or indeed any platform that I'm aware of) that will allow

I have a web application that lets the browser cache AJAX requests result for a long time. I have found out how to make a request that bypasses the cache entirely, when probable modifications are detected. But I would want to let the user trigger a data refresh. In this scenario, I'd like the browser to check with the server if the cache is stalled but use it if it is not (that is, if the server responds with a 304 code). The goal is to spare the loading time because the data is huge. The server includes the following headers in all responses: Cache-Control: private, max-age=604800 Last
