I would like to count the number of lines in a string. I tried to use this stackoverflow answer,

lines = str.split("rn|r|n"); 

return  lines.length;

on this string (which was originally a buffer):

 GET / HTTP/1.1

 Host: localhost:8888

 Connection: keep-alive

 Cache-Control: max-age=0

 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_2) AppleWebKit/535.2 (KHTML,like Gecko) Chrome/15.0.874.121 Safari/535.2

 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

 Accept-Encoding: gzip,deflate,sdch

 Accept-Language: en-US,en;q=0.8

 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

and, for some reason, I got lines='1'.

Any idea how to make it work?
