I have one doubt, does the clientID value unique and same ID won’t be used for other event ?. When this ID will be reused ?.

Hello

A clientID will never be reused for a connection while it exists in another and the same applies for http session id’s as well. Once the ID has been discarded, there is no guarantee as to when the ID will get used again (if it does).

Thanks,

Matt
