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:
caching - Difference between no-cache and must-revalidate for Cache . . . @Anshul No, must-revalidate and no-cache have different meaning for fresh responses: If a cached response is fresh (i e, the response hasn't expired), must-revalidate will make the proxy serve it right away without revalidating with the server, whereas with no-cache the proxy must revalidate the cached response regardless of freshness Source: "HTTP - The Definitive Guide", pages 182-183
Why both no-cache and no-store should be used in HTTP response? no-store should not be necessary in normal situations, and in some cases can harm speed and usability It was intended as a privacy measure: it tells browsers and caches that the response contains sensitive information that should never be written to a disk-based cache (or other non-volatile storage) How it works: Normally, even if a response is marked as no-cache by the server, a user agent
How to force Docker for a clean build of an image To ensure that your build is completely rebuilt, including checking the base image for updates, use the following options when building: --no-cache - This will force rebuilding of layers already available --pull - This will trigger a pull of the base image referenced using FROM ensuring you got the latest version The full command will therefore look like this: docker build --pull --no-cache
Sequence cache and performance - Stack Overflow If you omit both CACHE and NOCACHE, then the database caches 20 sequence numbers by default Oracle recommends using the CACHE setting to enhance performance if you are using sequences in an Oracle Real Application Clusters environment Using the CACHE and NOORDER options together results in the best performance for a sequence CACHE option is used without the ORDER option, each instance
How to disable webpage caching in ExpressJS + NodeJS? Beware of ETag Even if you are using nocache, the ETag header isn't removed, because it works in a different way It's generated at the end of the request and could be another source of unintended caching In order to handle it you have two choices app set The first is disabling it using express builtin app set('etag', false); method on-headers The second is removing the header just before
