in my error log i am seeing messages like this: 

2011/06/03 14:32:07 [error] 21125#0: *1768 connect() failed (111:
Connection refused) while connecting to upstream, client: 216.248.232.5,
server: MYDOMAIN.com, request: "GET /itsurvey HTTP/1.1", upstream:
"http://77.12.16.8:8081/itsurvey", host: "MYDOMAIN.com"


why is "upstream" connection being "refused"? and how is "upstream"
different from "proxy"? 

thanks for any ideas or advice.
