This is not directly part of forms, but as the redirect is most often used in conjunction with forms I guess, I will put it here.
I have added something like Director::redirect('page#anchor') at the end of a form action, and when I submit the form in Internet Explorer it just totally ignores the # and everything after it (It gets deleted in the URL in the browser's address line as well). If I just have a link with a # in it, that works fine in IE. It happens only when I use Director::redirect().
Does anybody have an explanation what is happening there, and how I could go round this problem?
