I have built a browser extension that, on startup, calls a web service from which it retrieves a JSON result. The JSON result contains data that will be shown in the popup of the extension. This data is updated at least once a day using a prepared, scheduled update service. Furthermore, the data is irregularly manually updated intra-day.
The data that is retrieved from the web service does not automatically adapt to the changes that are made. Particularly, the extension retrieves old results from the web service. The web service is tested and always returns the newest result, hence this is not a server-side problem (at least not with regards to the computation, storage and provision of the data).
I noticed that sometimes the web service appears to return old results, which then after a page refresh are updated. I believe this happens due to some caching mechanism(s) client- or server-side.
Researching the topic has not yielded any helpful resource or material
Is it possible for me to instruct the extension to not cache results from the web service and/or instruct the server to not allow/serve cached results?
Any advice and/or resource regarding this issue is very much appreciated.
