Hello everybody,
We are using nginx with php-fpm. Our application works as download aggregator. We download files from 3rd party servers and send it to client while it's still being downloaded. It means that we can't use X-Accel-Redirect, since file isn't fully downloaded and X-Accel-Redirect sets Content-Length to actual file size. We set required headers in php and in cycle read chunks of file, prints it and flush it to output. Everything seems to work fine except large files (over 1GB) on slow download speeds. Downloading was interrupted at 1GB - it seemed like client has disconnected - calling connection_aborted in php returned true. I have found out that fastcgi_max_temp_file_size is 1GB by default - so I have increased it to 2GB.
Now how exactly does fastcgi temp file works? Does every request has its own temp file? Or is there one common temp file?
Thanks for hints!
