In addition to automatically controlling what gets stored in the session history, I would really expect hitting the "Clear cache" button in prefs to clear form data from session history as well.
why? what does this buy us?
I believe the automatic controlling handles issues that are more about security, and it obviously won't be nice to always automatically clear all form data. Hitting clear cache seems like the intuitive way to do this, although historically this has been achieved by closing the browser window (? I never was sure why some sites asked me to close the window). What if I don't want to close the window? The session history shows me some useful sites I visited in this window and I use it as a convenient way of getting back to them. I actually use this way of getting to past URLs a lot (I can just jump over the pages that had form posts etc. and go directly to earlier URLs).
heikki: but even if we clear form data from session history, session history will still contain the forms from which the form data originated. moreover, layout history state will still fill in the forms as the user last saw them, so users would still be able to re-submit the forms if they wanted. so, i don't see the difference between that and having session history hold onto the accumulated form data. maybe the only difference is that the user would see the "must re-POST" error dialog instead of a broken page (or whatever we'd show if there wasn't form data with which to recreate the lost-from-cache page).
Hmm, maybe I stated things incorrectly. I want clear (memory) cache to clear layout history state that includes any information I have entered (scroll state is ok, if that is stored there, but I would be ok even if that was wiped out too)... One more thing to make it possible to wipe out all the information about session without closing windows or quitting the browser. Obviously needed more in kiosk mode. I am not claiming this is a high priority, but I do think this is a real issue.
sure, i see what you're getting at now... perhaps it almost would be better to have a clear session history button under the prefs for session history?? but, i still think closing the browser window is the easiest conceptually for users.
Perhaps, although I don't think it is clear to the users what session history contains. For example, I thought it only contained the URLs (based on the text in the pref for session history), and I thought cache contained the past pages, including the data I had entered in forms (this is also kind of implied in the text on the cache prefs page). Maybe we should have clear session history button, and in addition have a checkbox or something next to that button and clear memory cache button which, if set, would also clear the memory cache or session history, respectively. Or clarify things in the decriptive text. Or do both. I think we need to involve UI designers in this issue.
yeah, we definitely need to get some UI folks to comment on this.
