Bug: Can't redo preview page on DNS/server error

IE6 seems to cache the Preview page every time you hit Back and then press Preview again. This makes an intermittent error that prevents the Preview page impossible to recover from without launching a different browser (e.g. Opera), due to IE caching.

Test case

Intermittent - happened to me today for first time:

1. Edit a page and hit Preview
2. IE6 says 'DNS or server error' for some reason (just an Internet problem, not client or server IMO)
3. Hit Back button and then Preview again
4. Get the same DNS/server page, although TWiki.org is working for other pages

Follow up

Fix is probably to suffix ?t=nnnnnn to Preview URLs, just like RefreshEditPage. Since Preview pages should never be bookmarked, like Edit pages, I can't see any problem from doing this.

Doing a similar fix for ViewAfterSaveCachesOldPage would also be sensible.
