In your nginx configuration, there is no difference for the two 
server blocks configured except the uptream servers they proxy 
all requests to.

On the other hand, you claim that you've started two upstream 
servers:

"then I started the localhost:3003 and localhost:3002, each prefer 
to /www/wwwroot/www.demo1.com and /www/wwwroot/www.demo1.com."

Given the "prefer to" paths (whatever it means), both upstream 
servers seems to use the same configuration and expected to return 
identical responses.
