Hello all,
I am trying to develop a little program that should be able to send
http/1.1 requests. This is all running fine but I get some problems
with the persistent connection.
I mean I can send one request in my http connection but the second one
does not seem to work properly.
Maybe I made an error in my code, maybe I do not understand something in
http/1.1 ?
Can somebody help me please ? ... many thks.
