Jacques Le Roux commented on OFBIZ-5200:
----------------------------------------

Even if browsers "vendors" policies are more to update systematiqually, that sounds good to me (though I did not check all the response headers above, but I guess Roberto did it smartly)

> An user who is using IE9 might experience a strange behaviour inside a webpage with json ajax requests. This is so because IE9 does caching of these requests.
> I added in common/../CommonEvents.java , jsonResponseFromRequestAttributes method the following:
> response.setDateHeader("Expires", -1);
> response.setHeader("Cache-Control", "private");
> response.setHeader("Last-Modified", new Date().toString());
> response.setHeader("Pragma", "no-cache");
> response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");
