## Caveats and sources

Each one names the column it qualifies and cites the page it comes from, which is often not the page in the row's primary source.

### Legacy HTTP+SSE

The fallback triggers only on a 4xx response. Connection errors, timeouts, and 5xx responses are reported directly rather than retried on SSE, which is narrower than VS Code's negotiation.

### Sends resource (RFC 8707)

Sent by default as the server URL, and `oauthResource` overrides it. Setting it to an empty string omits the parameter from both the authorization URL and the token exchange, which the troubleshooting section names as the fix for identity providers that reject `resource`.
