Redirect Exchange 2003 OWA on Port 80 to Port 443

External Since: Nov 25, 2003 Posts: 2

I've been struggling with redirecting sessions that
connect on port 80 to our Outlook Web Access (Windows
Server 2003 & Exchange 2003) to HTTPS on Port 443.

I've tried changing the custom error message for 403.4 on
the Exchange VS to point to a URL /owaasp/owahttps.asp
with the following code, however when I enable it and
restart IIS Admin Service, instead of the redirect
happening sessions that connect on Port 80 get error 403
Access Denied:

<%
If Request.ServerVariables("SERVER_PORT")=80 Then
Dim strSecureURL
strSecureURL = "https://"
strSecureURL = strSecureURL &
Request.ServerVariables("SERVER_NAME")
strSecureURL = strSecureURL & "/exchange"
Response.Redirect strSecureURL
End If
%>

I have the Exchange VS set to Basic Authentication & Force
SSL & the /owaasp directory set to allow anonymous
connections. The directory structure is as follows:

C:\inetpub\wwwroot\owaasp\owahttps.asp
C:\Program Files\Exchsrvr\exchweb\bin

If I manually run the owahttps.asp page it redirects fine,
however it doesn't work like the following KB article
states:

http://support.microsoft.com/default.aspx?
scid=http://support.microsoft.com:80/support/kb/articles/Q2
79/6/81.ASP&NoWebContent=1

Someone suggested using the following code, which works if
I envoke it manually, but not of I replace the 403.4
error.htm page with this code:

<html>
<head>
<META HTTP-EQUIV="Refresh" CONTENT="0;
URL=https://mail.ocasf.org/exchange";>
</head>
<body></body>
</html>

Internet Explorer has this 'nifty' little feature that doesn't use the
error messages from the server, but gives a more user-friendly message.
If this is the browser you are using I'm willing to bet this is what's
stopping you. To disable this:

Tools->Internet options
Click on the Advanced Tab
uncheck the option that says "Show friendly HTTP error messages"

now try it again. This time it should pull the error from the server as
opposed to IE.

I too am having an issue with this, but have not found out anyway to
re-direct from the server without changes to the workstations.
