Here's the documentation: proxy_cache_bypass Defines conditions under which the response will not be taken from a cache. If at least one value of the string parameters is not empty and is not equa. I was not able to find documentation for output caching in Web API. Is this a limitation of the Web API in MVC4 or am I doing something wrong? In my web application I am setting window.location to navigate to a different page, but for some reason Firefox shows an old version of that page. Using Firebug I detected that the browser doesn'. I noticed some caching issues with service calls when repeating the same service call (long polling). Adding metadata didn't help. One solution is to pass a timestamp to ensure ie thinks it's a different http service request. That worked for me, so adding a server side scripting code snippet to automatically update this tag wouldn't hurt: That is, even though the web server sent a new app.nocache.js, the browser seems to have ignored that and kept using its cached copy! Goto Google- GWT Compile in Eclipse. you say when you press the back button on the browser and it displays the last screen, what is the last screen and where is the logout being called from? surely the last screen would be a logout page thus nothing really to see? But what I would like to do is to apply ?nocache=1 to every URL related to the site (including the assets like style.css) so that I get the non cached version of the files. Últimamente me he visto con muchos problemas en Google Chrome (en otros navegadores me va bien, exceptuando también Safari en Mac) al momento de cargar una nueva versión de una hoja de estilos (.cs. Personally I feel that the query string method is more reliable than trying to set headers on the server - there's no guarantee that a proxy or browser won't just cache it anyway (some browsers are worse than others - naming no names). I usually use Math.random() but I don't see anything wrong with using the date (you shouldn't be doing AJAX requests fast enough to get the same value twice). From fastapi official doc The --no-cache-dir option tells pip to not save the downloaded packages locally, as that is only if pip was going to be run again to install the same packages, but that's not the case when working with containers. Basically, there is no need to store whatever package cache you're installing locally since it is not required by docker containers.
