Stanislas,

That part is irrelevant. I will have separate sub/table to store all session ids to be able later on to retrieve all ips per session.

My main concern here was to optimize adding new ips as a list to table key value.

Based on Kai advice I think final solution is:

 

if {[table lookup $sess_id] eq ""} {

    table set $sess_id [IP::client_addr]
} else {

    if { [lsearch [table lookup $sess_id]] == -1} {

        table append $sess_id " [IP::client_addr]"

    }
}

 

What do you think?
