Irule logic question

Hi Lee,

I sometimes find it easier to read an iRule (especially when you include NOTs) by breaking the 'or' into separate 'if' conditions. Notice the "!" - this makes the condition a NOT.

So:

IF NOT datagroup URI, IF NOT datagoup IP, drop. (everything else will be allowed)

when HTTP_REQUEST {
    if {(![class match [string tolower [HTTP::uri]] contains Allowed_uri])} {
        if {(![class match [IP::client_addr] equals Allowed_IP])} {
            drop
        }
    }
}

PS -

matchclass
