Hi, everybody,

Please give me a hand.

In VOD system, Nginx is reverse proxy and Lighttpd is application server  
with video files. And getting video files is the type  
“play.jsp?videoid=123456”.

Now , I want to cache video files in Nginx server from dynamic link with  
“?”. How to define the Nginx configure?

Thanks & Regards

George yuan
