From what I can tell, there is no way to retrieve multiple values with a single get request, so looking for the last instance of crlf + "END" + crlf should be fine. However, if I am misinterpreting, and the code needs to be able to handle multiple VALUE...END pieces, let me know and I will change lastIndexOf() to indexOf()

result_len = end_indicator_start - first_line_len;

Since the index retrieved on the above line now includes a crlf, there is no need to subtract the crlf_len.

result_value = buffer.substr(first_line_len, result_len);
return [result_value, first_line_len + parseInt(result_len, 10) + crlf_len + end_indicator_len + crlf_len]
} else {
