What should the URL start with in an ICAP profile? ICAP or ICAPs

Hi Wasfi_Bounni , 

Okay , 

using internal Virtual server you have ( Server ssl profile ) you must add it , by adding it between Bigip and ICap server so >>> Bigip will be able to establish a secure connection with ICAP servers. 

So First add ( server ssl ) on the internal virtual server that sends ICAP requests to your ICAP servers. 

the second thing >>> I haven't seen icaps protocol before. 
So I'm recommending this :  icap://${SERVER_IP}:${SERVER_PORT}/virusScan .

Like I said >>> Bigip can open a secure connection with Icap servers by using server ssl profile in internal virtual servers.

Try this and give me your feedback.
