Dear list,  
I am testing nginx with reverse proxy mode.  
I found that nginx download the file from upstream server to  
proxy\_temp\_path when I download a file from the reverse proxy server,if  
I stop and re-download,the nginx will download the file from upstream  
server again,and so on.  
The problem is when a large file on a site,someone could launch  
malicious multi-threaded connections to attack the reverse proxy server  
and upstream server.  
any configuration to limit it?

Another problem, when I pause and resume to download, and nginx has not  
finished download from upstream server,it would show the message:the  
server error.But when the file cached,it works fine.

Best
