Download Large Files Directly

Server NGINX
1

Hy @ All,

Is there an Option in nginx to set a limit for the download filesize, so
that the requested file will be downloaded from the proxied server
(apache) directly?

Example:

testfile.bin over 10 MB, will send directly to apache

Client --> Apache

testfile.bin under 10 MB, will send to nginx cache and then to apache

Client --> nginx Cache --> Apache

Any Solutions?

Regards,

Maik U.

Client → Apache

testfile.bin under 10 MB, will send to nginx cache and then to apache

Client → nginx Cache → Apache

Any Solutions?

You can implement the following solution:

  • any request passes to the Apache
  • probe the file size
  • if size over 10MB - serve it like you want
  • if under - send X-Accel-Redirect response to nginx

XSendfile | NGINX

Let me explain this with a other way:

if the file has a size over 10 MB then nginx will not cache the file in
the filesystem and it will downloaded directly from the apache

if the file has a size under 10 MB then nginx will cache the file in the
filesystem
