iRule to catch 4XX and 5XX HTTP error codes.

Hello Folks,

Got a similar one, thought to share.

when HTTP_REQUEST {
    set hostvar [HTTP::host]
    set urivar [HTTP::uri]
    set ipvar [IP::client_addr] 
    }
    when HTTP_RESPONSE {
            if { [HTTP::status] starts_with "5" } {
                    log local0. "$ipvar requested $hostvar $urivar and received a [HTTP::status] from [IP::server_addr]" }
    }
