!Server/Profile Parameters

For a reliable HTTP communication set the following
|icm/server_port_0	|PROT=HTTP,PORT=xxxx,TIMEOUT=120,PROCTIMEOUT=3600
|icm/server_port_2	|PROT=HTTPS,PORT=xxxx,TIMEOUT=120,PROCTIMEOUT=3600
|icm/keep_alive_timeout	|120
|icm/conn_timeout	|20000
|icm/HTTP/client/support_http2 (???)|FALSE

If icm/HTTP/client/keep_alive_timeout=0 is used, HTTP Keep-Alive is disabled altogether when acting as client. This solution affects all outbound HTTP connections.

!HTTP keep-alive
Use HTTP 1.1 with
{{{
lo_http_client->request->set_version( if_http_request=>co_protocol_version_1_1 ).
}}}

If you use it within HTTP header you need to set Connection=keep-alive, too!
{{{
HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: text/html; chartset=utf-8
Keep-Alive: timeout=10, max=100     
}}}      

!ICM log
"BINDUMP of content denied" => icm/trace_secured_data = FALSE (TRUE or 1/0)
