   Fix now available for Page Redirect issue
   This page last updated on November 21, 1997

   Microsoft is now providing a fix for a potential problem known as th=
e
   "Page Redirect" issue.

   Who is affected
   Users of the following versions of Internet Explorer could be affect=
ed
   by the Page Redirect issue:
     &#149; Internet Explorer 4.0 for Windows 95 and Windows NT 4.0
   &#149; Internet Explorer 3.02 for Windows 95 and Windows NT 4.0

   Note: The Page Redirect issue does not affect Internet Explorer for
   Windows 3.1, Windows NT 3.51, or Macintosh. It does affect Preview 1
   of Internet Explorer 4.0 for UNIX. Please note that Microsoft
   recommends using preview versions for evaluation purposes only and
   will fix this issue in the final version of Internet Explorer 4.0 fo=
r
   UNIX. In the meantime, we advise that UNIX Preview 1 users do not
   enter their authentication information at Web sites.

   How to protect your computer
   Download the patch below for your version of Internet Explorer to ge=
t
   the easy and complete fix for the Page Redirect problem:
     * [15]Download the Internet Explorer 4.0 for Windows 95 and Window=
s
       NT 4.0 patch
     * [16]Download the Internet Explorer 3.02 for Windows 95 and Windo=

   About the potential problem
   When you connect to a site that requires basic user authentication
   information (name and password), and the Web site redirects you to
   another Web site, your authentication information could potentially =
be
   captured by the second Web site. It can only be captured if the Web
   site has malicious intent and uses special techniques to obtain the
   authentication information.

   Microsoft has received no reports of any Internet Explorer user bein=
g
   affected by this problem to date.

   Language availability
   We are working on various localized versions of this patch and will
   post them as they become available. Check the download link above fo=
