[Zope] Internet Explorer does not follows redirect, while Firefox does

Thu Jun 1 06:49:49 EDT 2006

Ok, I've been able to experiment. All my pages have the following in
the <head> section:

        <meta http-equiv="Cache-Control" content="no-cache">
        <meta http-equiv="Pragma" content="no-cache">
        <meta http-equiv="Expires" content="Date.Now">
        <meta http-equiv="Pragma-directive" content="no-cache">
        <meta http-equiv="cache-directive" content="no-cache">

Also, I added, before every redirect, the following:

        request.get('RESPONSE').setHeader('pragma', 'no-cache')

Any suggestion?
