Sorry, I've assumed you were talking about Back button only. In case of Refresh it depends whether user realizes implications of re-submitting. If browser designers don't believe that pressing Refresh button states intent clearly enough, then I think asking the question might be justified. As creator of application you can solve this dylemma: * If it's not safe to resubmit, use status 303. I know it's not very convenient, but can be implemented reasonably well and works with existing browsers. * If it's safe to resubmit, use PUT method (allowed in HTML 5), which is idempotent by definition. -- regards, Kornel Lesinski
