Rate limit http and https requests globally

I guess you could do this with tables, but you'd have to assign this to all virtual servers and they'd have to use an HTTP profile.

Try something like this?

when HTTP_REQUEST {
    set lifetime 1
    set requestlimit 10

    Add a table entry with a lifetime in seconds of the value of $requestlimit.
    table add "Globalcount" 1 indefinite $lifetime

    set currentcount [table lookup -notouch Globalcount]

    if { $currentcount < $requestlimit } {
        table incr -notouch "Globalcount"
        HTTP::respond 200 content "All fine"
    } else {
        HTTP::respond 503 content "Limit reached $currentcount"
    }
}
