Here’s a quick tip, if you’ve configured Dynamics CRM 2011 to use SSL (e.g. for IFD) and you have users who are still on IE8 you’ll notice that IE8 doesn’t cache the secure responses. Therefore each time you open a form it’ll make 100-200 requests! It also brings another quick which forces users to double click twice on grids to open records.
To fix this issue clear the value in Internet Explorer Options > Advanced > Security > ‘Do not save encrypted pages to disk’.
