I have an http software that let people be logged and download data according to sent bytes. It's an infinite download until connection stopped. I want to know the time for each download.
The connection is like that:
- Curl start login with header/user etc
- HTTP server answer and start connection
- curl send bytes -> the server answer each times
Before, I were using only curl -so /dev/null -w '%{time_total}\n' http://my-ip.com:port/something -u login:passwd to know the total time, but it's only for the connection, not really the actual latency as real users could have, so it's not what I want.
I tried something like that:
curl http://my-ip.com:port/something -u login:passwd --header "Connection: Keep-Alive;User-Agent: curl;<omitted output>" --output "<output file>"
Where
omitted outputcorrespond to internal valuesoutput filecorrespond to the answered data by the server
But the -w 'thing' filter no longer works, as the request never finished. How can I make it works to get the latency each time I get answer?
