If the no-cache directive does not specify a field-name, then a cache MUST NOT use the response to satisfy a subsequent request without successful revalidation with the origin server. Alconja’s answer is the answer to the question, specifically. Are there differences between browsers? No-store is effectively the full do not cache directive and is intended to prevent storage of the representation in any form of cache whatsoever. If the server says that the resource is still valid then the cache can respond with its representation, thus alleviating the need for the server to resend the entire resource. Must-revalidate, on the other hand, only needs to revalidate when the resource is considered stale.
Open the page in cognito mode just to get-rid of cache issue and unblock yourself. Ideal HTTP cache control headers for different types of resources. And then make sure to set the correct caching headers before reloading the page, see e.g. It may have decided long ago, that it will never have to reload the resource again. I’ve seen a bit https://expandsuccess.org/adapting-to-technology-in-leadership/ 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).
After logging out from our website you could press the back button and view cached pages. I’m adding the headers in a reusable middleware, otherwise you can set those headers in any way that works. Ok, even if you aren’t using express, what essentially needed is to set https://carsinfo.net/ukrainian-service-it-company-integrity-vision.html the nocache headers. But I don’t know how to use it because I get errors when I put that line in my code. In the header.php file and that has solved my issue.

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. Other Cache-Control parameters such as max-age are https://californianetdaily.com/what-happens-after-you-complete-a-python-automation-course/ irrelevant if the abovementioned Cache-Control parameters are specified. The Expires is per the HTTP 1.0 and 1.1 specs for clients and proxies. The Pragma is per the HTTP 1.0 spec for prehistoric clients. The Cache-Control is per the HTTP 1.1 spec for clients and proxies (and implicitly required by some clients next to Expires).
