function backdrop_set_length_headers($content_length) {
// Set the total content length.
backdrop_add_http_header('Content-Length', $content_length);
// If using chunked content (enabled with Apache mod_deflate), then specifying
// the content range is required. This delivers the entire page in one chunk.
backdrop_add_http_header('Content-Range', '0-' . ($content_length - 1) . '/' . $content_length);
