Is it:
GET api/stuff?ids[]=123&ids[]=456&ids[]=789&ids[]=101112&etc...
is it:
POST api/stuff/batch
body: ids: [123, 456, 789, 101112, etc]
?
The first seems semantically correct, but aside from having an incredibly gross url, there are sources that say there's potentially a limit for the length of a get, so what if I have a gazillion ids?
The second seems better because there's no gross url, but my understanding with rest is that a POST is supposed to be making a change, not be idempotent..
So is this purely a semantic issue and there's no true "correct" way?
