in reply to Re^5: Dancer::send_file only for POST?
in thread Solved: Dancer::send_file doesn't work with POST? ( Angular JS hijacks the response)

Thanks Corion. The confusion in the OP was entirely my fault.

I implemented a redirect but the result is the same: the print statement, which I placed immediately before the redirect, is output but then nothing in browser or log.

The way forward always starts with a minimal test.
