`app.use(cache('5 minutes'))` will cache all routes, regardless of methods like `GET` and `POST`

See original GitHub issue

It turns out if we do app.use(cache('5 minutes')), it will cache all routes, regardless of methods like GET and POST. However, for methods like PUT and POST, in many cases this implied update on the server side and shall not be cached. Should we add documentation or functionality to make supporting such case more easily?

I don’t think that PUT,PATCH,DELETE should ever be cached. POST is a gray area because the SOAP protocol uses POST for everything, although that technology is on the way out.

It could be built to ignore POST (and PUT,PATCH,DELETE) in the app.use(cache(…)) pattern, and if anyone needs post caching they could add it on the route explicitly. This seems like a good default behavior. It does sound like a “fixing expected behavior” fix to me.

Something I would say is that I’ve used GraphQL APIs where the request was submitted as a POST request but I’m not sure how common that is.
