Hi all. I don't think this is a specific Zope problem. However, I'm experiencing it in a Zope context, and this is why I'm here asking. In a custom Zope application, we have a problem with Internet Explorer. The application follows a "page -> submit -> redirect -> page" cycle. To state more clearly: the page presented to the user can have a link. When the user clicks on the link, something is done, and eventually the user is redirected to the same page which will display different data based on the results of its previous click. The problem is that when IE sees that the result page has the same URL as the first page it does not reload the page and instead shows me the cached version. The problem is not shown with Firefox. As far as I can understand, this is an HTTP header issue, but I would like to know if anyone already has experienced this problem, and has some solution about it.
