Ticket #11894: MAF.with.close.protocol

File MAF.with.close.protocol, 6.4 KB (added by Bill Meek <keemllib@…>, 13 years ago)

Capture with client modified to send Connection Close (same result as using the patch)

21st PSH message. The result is the same as if MythTV received Keep-Alive
3and responded with Close. I have that protocol too.

5The following was done with unmodified MythTV code.

7Normal 3 way handshake and PSH, nothing new here:
