# http/sse-comment Send an SSE comment line — the manual keep-alive form. Comments are ignored by `EventSource` clients but keep the connection and intermediaries alive. ## Syntax
[http/sse-comment $stream "text"]
## Parameters - `$stream` — `%SseStream{}` from `http/sse` - `$text` — comment text (string) ## Examples
[http/sse-comment $stream "still here"]     # → true
## Returns `true`; `%Err{:message}` when the stream is closed, the first argument is not a stream, or `$text` is not a string. Emits `: <text>\n\n`. ## See Also `http/sse`, `http/sse-send`, `http/sse-close`
