When we try to define ACO parameter HttpsPorts with multivalue with values 80 and 443 I got the following in the webagent.log
[4324/6064][Thu Jul 06 2017 19:10:04][LLAWorkerProcess.cpp:1520][INFO] LLAWP: Received update for agent configuration object 'dealer.rete.poste_new_aco'.
[4072/2184][Thu Jul 06 2017 19:10:17][CSmHttpPluginConfig.cpp:2231][ERROR] Invalid configuration: 'httpsports' has been specified more than once; using default value.
httpsPort ACO is defined as multi-value
Please define httpsPost as single value and different ports separated with coma (",").
