Client-side pipelining using simultaneous sessions with keep-alives is usually severely restricted on server-side (exactly for the reason they can be abused to DoS the server), and the overhead is much higher (you need to send hundreds of bytes to request a copy of a static page). Here, requesting an extra copy costs you 3 bytes, and that is in my opinion notable - because you can do it thousands of times in a single short request. > If you have an issue with this behavior, of HTTP, then you have an issue > with the behavior under FTP or a host of other protocols. Not really; see above. These are typically well known, preventable by configuring server-side limits, and require a much higher overhead. /mz
