Question on incoming headers need to copy

[quinnj]

For the on_incoming_headers function:

typedef int(aws_http_on_incoming_headers_fn)(
    struct aws_http_stream *stream,
    enum aws_http_header_block header_block,
    const struct aws_http_header *header_array,
    size_t num_headers,
    void *user_data);

is it required to make a copy of each header to be used at the application level? Or is there some guarantee that the headers will stay alive for the life of the connection? I know the aws_http_on_incoming_body_fn mention explicitly that the incoming data must be copied, but it's unclear if headers are the same in that regard or not.

The headers must be copied. There is no guarantee they will stay alive beyond this callback.
