i have ngnix mod in main server and one of file server download with ngnix port without have ngnix mod on it so download error
i think i need to have mod_headers
actually, i don't think you neeed nginx on your main server. to my understanding, you need nginx on your file server though. if you enable nginx in settings then all file servers must have nginx. If not then the file servers that don't have nginx will not work.
how about you define `download error`, if you get x can't find the server at apache.yourwebsite.com:182 or something like that you need to change the apache to also listen on that port...
