Optimize Emscripten REST long-poll requests - #410
Merged

Conversation
Send Content-Type only for POST requests while retaining Accept for GET and long-poll requests. This avoids unnecessary OPTIONS requests without changing response content negotiation. Signed-off-by: drslebedev <dr.s.lebedev@gmail.com>
Use EMSCRIPTEN_FETCH_REPLACE to skip Emscripten's implicit IndexedDB lookup. REST responses are not persisted and should be fetched directly. Signed-off-by: drslebedev <dr.s.lebedev@gmail.com>
