Re-balance requests from a single client

Try this one:

when RULE_INIT {

    set static::lifetime 60
    set static::requestlimit 10

}

when LB_SELECTED {

    if { [HTTP::header "User-Agent"] contains "Mozilla" } {

        Add a table entry with a lifetime in seconds of the value of $lifetime.
        table add [IP::client_addr] 1 indefinite $static::lifetime

        if { [table incr [IP::client_addr]] > $static::requestlimit } {
            If the user has surpassed the request limit the pool member is reselected
            log local0. "This server was selected: [LB::server]"
            LB::reselect
            log local0. "Selected [LB::server]"
        }
    }
}
