Homework and Emergencies Emergency UNIX and Linux Support Netcat ( nc -l ) as webserver Post 302987765 by chakrapani on Thursday 15th of December 2016 10:46:38 AM
Old 12-15-2016
I made a named pipe and seems very close to getting my solution of garbing HTTP headers, Also noticed my browser does not Always send all the header each time.
(Chrome Version 54.0.2840.99 even in incognito )

My workaround (not solution) have a named pipe to communicated with nc.

Code:
$ mkfifo  webout

and then have the while loop to feed netcat(nc)

Code:
while true; do { echo -e 'HTTP/1.0 200 OK\r\n'; cat webout;  } | nc -vl 8080 >webout; done

I am just playing around with named pipe, looking to find something in the lines of:

Code:
nc -l PORT <webin > 2&1>webout

and then loop out with tail kind of thing on webin and webout. Any experts on FIFO's please suggest.
