Re: Fetching Web Page Inconsistent

[Patrice]

Hi,

Do you always have the same behavior on a given machine or does it work
sometimes and sometimes not ?

Have you checked if it depends on wether or not the browser uses the new
"protected mode" ?

Also what is the authentication method ? Is this web app under your control
? Have you checked the http status code ?

In particular I found :

http://support.microsoft.com/kb/932118/en-us - Persistent Cookies are not
shared between IE7 and Office apps in Windows Vista (caused by protected
mode).

I don't have IE8 handy.

FYI you also have a protected mode API
(http://msdn.microsoft.com/en-us/library/ms537312(VS.85).aspx) that could
perhaps help (it seems to be able to retrieve the protected mode cookies) if
users are not supposed to change in which zone this web site is running.
