Hello Wasfi,
Thank you for reaching us.
After checking, it appears you are refering to our Web Security Services (WSS) product, different than our Web Security.Cloud, tagged on this post.
We do not use Client Connector in Web Security.Cloud offering, and despite digging, I cannot provide you with a complete solution to this question, as I lack on-hands knowledge of this feature.
I would adivise you to make a new post for the product Could-Delivered Web Security Services tagged, or contact the support team for this product through a support case, to get a preceise answer to your request.
Have a nice day!
Best regards,
Guillaume Pietkiewicz,
Pr. Product Support Engineer, Symantec.Cloud
