This is extremely basic HTTP server.
Thing is that I don't want to provide Content-Length.
The problem is that when I close the connection from server side,
Firefox and curl most the times claim the connection is broken.
Without closing the connection they're stuck.
What I'm doing wrong?

beyondlimits / 7zlist
Created December 29, 2018 16:34
File list can be obtained by running either:
7z l FILE (for a short list)
7z l -slt FILE (for a long list)
Examination of the outputs of both commands led to following observations:
- Both commands produce output with common header when run with the same
archive file using the same version of 7-Zip.
