Hi, Lisa et al, This is commonly considered a best-practice design pattern. Specifically,
* Any submission causing side effects (non-idempotent) should be done via POST rather than GET. * No POST handler should ever return anything but a redirect to the browser. As you point out, this eliminates the resubmit-on-reload problem. It also makes the browser's back button behave properly, interacts better with cache management, and so forth. I do not believe there is any particularly high overhead associated with this pattern. On 5/27/07, Lisa Klein <[EMAIL PROTECTED]> wrote: > Hi, running the lastest Mason under Apache and mod_perl.
