ElI5 why is the ‘cache’ this all powerful crasher of apps and causer of problems? Why does clearing it fix things?
In: 101
Simplest terms, a Cache is a local storage. In the context of the question it is often configuration or state information that is being stored locally. For the most part this information is stored to increase load times or remember information about something (like a login).
The reason clearing a cache often solves problems is because the source of the information (server, website, etc) cannot control the data in the cache, but the cache is being used to interact with the source.
Example, let’s say you change your login information. For whatever reason it is cached locally from before the change. At this point the local login information in the cache no longer matches the real login information. It either needs to be deleted or updated.
