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

Fri Jun 2 00:17:53 EDT 2006

I have forgotten the exact details, but some time back I found it 
necessary to pad out the body of the redirect page in order to make IE 
perform as intended. It may have been for an older version of IE, and 
the padding just needed to be a certain number of bytes. I think I came 
across a later reference to the problem. Have you googled for info? 
Padding follows.
