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
