Internet Explorer kwam telkens met de volgende melding als we bestanden van onze https (ssl) site probeerden te downloaden: Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later
Dit bleek aan een Internet Site Rule te liggen die Caching moet voorkomen. De No-Cache rule was echter nodig om te vookomen dat formulieren worden gecached. Als oplossing hebben we nu voor de meest voorkomende bestandstypes andere rules aangemaakt.
Firefox heeft dit probleem overigens niet.
Op de Microsoft support site stond dit als oplossing: http://support.microsoft.com/default.aspx?scid=KB;EN-US;q316431
