I understand there is a HTTP response header directive to disable page caching: Cache-Control:no-cache I can modify the header by "hand": <%response.addHeader("Cache-Control","no-cache");%> But is there a "nice" way to make the JSP interpreter return this header line in the server response? (I checked the <%@page ...%> directive....
I have some static images in a folder on my IIS 6-based website that I want to be downloaded as little as possible (to preserve bandwidth). I've set the Content Expiration to expire after 30 days. Is there anything else I can do in IIS to try to maximize the caching by browsers, proxy, and gateway caches? Such as adding a Cache-Control ...
Recently I read a software engineer job description. The requirements included knowing how the web works from HTTP to HTML, improving the performance of the TCP stack in Linux, and knowing how cache-control headers work. What's the best way to learn about these topics? ...
I'm running into some HTTP caching issues, caused by some downstream apps not putting Cache-Control headers on time-sensitive data. I need to make the case that this is a broken situation. Is there any succinct statement available online about permissible or common response-handling behaviors by caches and agents when the Cache-Control ...
Good day, I am using CacheFilter to filter a certain path to my server (which outputs an image stream to the response stream).

I do not want my Java SWT application to cache temporary internet files. Currently I am dealing with IE (because SWT uses the native browser), and the browser cannot be changed. The "Cache-Control: no-cache" seems to work fine for every file type I display, except wmv. My "Expires" is set to 0. I have tried all kinds of cache control co...
When you explicitly set the cache request and response directives via setting response and request headers, is there a better way to test if they are working correctly for UAs other than manually looking in their cache? On a related note, am I right in assuming browsers get the current time for cache operations from the computer's syste...
Problem: I can't seem to get FireFox to cache images sent from a dynamic server Setup: Static Apache Server with reverse proxy to a dynamic server (mod_perl2) at backend.

I was reading this: http://docs.codehaus.org/display/JETTY/LastModifiedCacheControl It says "The Jetty default servlet allows the cache control header to be set for static content by using the cacheControl init parameter using <init-param> <param-name>cacheControl</param-name> <param-value>max-age=3600,public</param-value> </init-par...
I am using Resin 3.2. According to the documentation I should be able to tell Resin to cache items of my choosing by inserting the following into the resin-web.xml within the webapp element.

Below is an example on how to cache all files on the server ending in html or htm for 2 hours (7200 seconds). So how would I go about doing this only for the homepage of the website, but not any other URL? <FilesMatch "\.(html|htm)$"> Header set Cache-Control "max-age=7200, must-revalidate" </FilesMatch> I tried a Directory and a Loca...
I'm creating a RESTful API (using MVC.NET) to allow external access to a business system. The API includes a search resource. The resource takes the URI form "/example/search/pages/1/?query=something". Example: To search for pizza you would access the URI "/example/search/pages/1/?query=pizza" which would give you the first 10 resul...
Scenario: I have a base controller which disables caching within the OnActionExecuting override. protected override void OnActionExecuting(ActionExecutingContext filterContext) { filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)); filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false)...

But on our prod we have multiple apache servers having aliases to a code base on a different server. Here in this case i am not sure where ...
I have to have several certain cache-control directives set on an ASP.NET page in order to pass a Hailstorm security scan. For example, it wants me to have Cache-control: no-cache="set-cookie" in addition to Cache-control: no-cache I have been setting the latter with the following line in my C# codebehind: Response.CacheControl = "n...
I have a couple of queries related to Cache-Control.
