If I understand correctly, you want this:
- client opens connection, server accepts it
- client sends nothing
- server sends a pre-defined file
- server closes connection

Assuming you have a linux server, simple inetd service is enough.

/etc/inetd.conf:
....
adobe stream tcp nowait nobody cat /path/to/the/file/to/be/sent
....

/etc/services:
....
adobe 843/tcp
....

Both these files should include the given lines, the ... means there are
other lines that should probably be kept.

Not tested, but should work. No nginx needed, it's an overkill for this.
