Supporting ETag and if-none-match

[RobertGardner]

My server supports ETag and if-none-match on some requests with large payloads, but SWR doesn't seem to pay attention to these out-of-the-box. What is the suggested technique for supporting these?

@RobertGardner Have you found any solution to this? I'm struggling to figure out how to use refreshInterval without sending all of the data back each time if I know the client has the latest. Does anyone have a suggestion for that?

I ended up implementing a custom fetcher that implemented the ETag logic. Not the greatest but it worked and wasn’t very hard. Unfortunately, I no longer work at that company so I can’t access the code to provide more details.
