IMHO what you are describing is a browser that is not following your suggestions, a fix of the client will stop this, however your app should be rebust enough to cope with all kinds of non standard client behaviour including malicious behaviour. It is after all the client that has ultimate responsibility for following the headers or not, so you will not be able to force a change on a particular user-agent. My advice therefore is to forget the problem, unless it is a show stopper for your clients, in which case they are responsible to some extent for ensuring their software is up to date and compliant. If this approach is not practical, then you will have to change the terms and conditions to allow for this eventuality - which will crop up again. -- Matthew Farey --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
