I have seen some other annoying behaviour on older MSIE browsers which could propably also be cured with the Pragma-no-cache: and/or a properly set Expires: header, in that those browsers display cached versions of the pages all the time (which might even be the correct behaviour). This is a bad thing when doing dynamic stuff such as displaying a "you're logged in as ..." line on each page.
Is there a standard way in OpenACS 4.x to make it add such headers all the time? If not should we add such an option?
