Our requirement came from a security test. After logging out from our website you could press the back button and view cached pages. I only want the caching to be applied to specific actions, not for all actions. You can use nocache Middleware to turn off caching. So now anything related to the docker is gone and docker cache is completely deleted , like you have a fresh docker installation .
As you identified, no-cache doesn’t mean there is never caching, but rather that the user agent has to always ask the server if it’s OK to use what it cached. By contrast, no-store says to not even keep a copy, which means there’s nothing to ask about. If you know the answer to “Can I reuse this?” is always no, you get a performance boost by skipping cache validation and saving room in the cache for other data.
Manage your data
- After unsuccessfully preventing caching via Apache I created a bash script that root runs every minute in a cron job on my Linux Tomcat server.
- As pointed out in the comments this is actually a “ten-liner” package but it belongs to the Helmet project, a long running initiative to secure Express applications.
- I only want the caching to be applied to specific actions, not for all actions.
- For detail, see IE cannot download foo.jsf.
- Built-in shortcuts to Google apps let you check your calendar, hop on a video call, or check off to-dos without missing a second, or opening another tab.
The Last-Modified header as included in most other answers here is only interesting if you actually want to cache the request, so you don’t need to specify it at all. You can use the built-in cache attribute to prevent caching. Note that if your docker-compose file references an image, the –pull option will not actually pull the image if there is one already. The list is just examples of different techniques, it’s not for directinsertion. If copied, the second would overwrite the first and thefourth would overwrite the third because of the http-equivdeclarations AND fail with the W3C validator. At most, one could haveone of each http-equiv declarations; pragma, cache-control andexpires.
Get Chrome
It looks dirty, but as far as I know it’s the most efficient way to continue benefiting from the cache system of Docker, which saves time when you have many layers… In most of cases, these 3 things are perfectly enough to allow a clean build of our image.So we should try to stick to that. To prevent caching the update and install separately.
Find the right Chromebook for you.
Use this middleware where-ever you intend to turn caching off. However, cacheing headers are unreliable in meta elements; for one, any web proxies between the site and the user will completely ignore them. You should always use a real HTTP header for headers such as Cache-Control and Pragma.
- ETag (MDN reference)If you have dynamic content which does not benefit from ETags, it’s best to disable it because it incurs small overhead with each request.
- Removable keyboards give you the freedom of a tablet with the ability to add standard typing when you want.
- Client would ask server if it has new version of data using those headers and if the answer is no it will serve cached data.
- Additionally, jQuery and other client frameworks will attempt to trick the browser into not using its cached version of a resource by adding stuff to the url, like a timestamp or GUID.
- Thus, the user can navigate backward to a previous page with no-cache without the server being contacted.
- Automatic updates keep your Chromebook feeling fast and up to date by downloading the latest software and security features behind the scenes – without interrupting you.
I want to set those headers on file downloads too
After redirecting on ActionFilterAttribute event the consequences of clearing all headers are losing all session data and data in TempData storage. It’s safer to redirect from an Action or don’t clear headers when redirection is taking place. On a more positive note, policies regarding physical access to computers, software installation, and the like will put you miles ahead of most firms in terms of security. In the old HTTP spec, the wording was even stronger, explicitly telling browsers to disregard cache directives for back button history.

2 The RGB feature is only available on specific Chromebook Plus devices. Built-in shortcuts to Google apps let you check your calendar, hop on a video call, or check off to-dos without missing a second, or opening another tab. 5 You must be connected to the internet to set up this feature. Must have available storage space in Google Drive. Basically, there is no need to store whatever package cache you’re installing locally since it is not required by docker containers.
They offered a code to disable it directly into your wp-config.php file. SpinyBet bonus Find centralized, trusted content and collaborate around the technologies you use most. Find accessories designed specifically for Chromebook.
Full feature availability requires you to be signed into your Google Account on all devices. 3 Actual battery life may be lower and will vary significantly based on factors like network conditions, location, settings, and usage. Full feature availability requires you to be signed into the same account on all devices. The Connected devices setting must be enabled. Wi-Fi networks without passwords are not synced. 2 Full feature availability requires you to be signed into your Google Account on all devices.
You need to configure cache time as mentioned in others comments. I’ve seen a bit of strange behaviour in Chrome’s dev tools with the network tab in combination with caching (at least, it’s not 100% transparent for me). In case of doubt, I usually still consult Firebug. By default, my browser caches webpages of my ExpressJS app. Sample code in Python using web.py web.header calls follows.
