Browsers should validate freshness of cached stale written content just before using it, but It's not mandatory unless the additional directive will have to-revalidate is specified.
These directives does not mitigate any security possibility. They are really meant to force UA's to refresh risky information, not hold UA's from being retaining information.

This issue has been driving me mad for just a few months now, body seems to really know the way to deal with cache control.
When you don't care about IE6 and its broken caching when serving pages around HTTPS with only no-store, then you could potentially omit Cache-Control: no-cache.
window.onbeforeunload = perform () // This functionality does almost nothing. It will not likely spawn a confirmation dialog // But it will eventually make certain that the page is not cached by the browser.

Note that https is needed because Opera wouldn't deactivate history buffer for plain http pages. In the event you really are unable to get https therefore you are ready to dismiss Opera, the best you can do is this:
In other words and phrases NoCache attribute won't leak to other actions if they execute little one actions. Also, the class name need to be NoCacheAttribute to comply with generally recognized naming convention for characteristics.
7 Will not set up this offer to save lots of 4 lines of code. Cutting down dependencies should usually be amongst your targets. Every dependency you increase is another point that needs being updated, another way to get your project hacked, another strategy to insert even more dependencies if this package adds dependencies, and so forth.
In the event you have dynamic content material which does not profit from ETags, It is really best to disable it as it incurs small overhead with Every single request.
Is there an attribute that I can placed on an action to ensure that the data does not get cached? Otherwise, how can I guarantee that the browser will get a fresh set of records each time, instead of a cached established?
Joseph ConnollyJoseph Connolly 9451111 silver badges2121 bronze badges 2 one For World wide web.config I'd modify just a bit to use the custom headers only for those scripts which we know are loaded dynamically / applying requirejs. Assuming your scripts are present in client folder: .....
There is just not much you can do about these. The good news is that they typically cache for shorter time frames, like seconds or minutes.
one The solutions here are all sad. I would increase my very own, but This is often closed. According to MDN: developer.mozilla.org/en-US/docs/Net/HTTP/Headers/Cache-Control you do in fact most likely desire check here to use as in the question.
