Redirect HTTP connection to HTTPS

We've all experienced it with setting up an Exchange Server with Outlook Web Access (OWA). Users are connecting with HTTP while they should use HTTPS. Normally they would get an 403.4 error when connecting with HTTP, telling them to use HTTPS, which they have to type in manually. Wouldn't it be easier if they were redirected to HTTPS? With IIS 6 you can do just that! Follow these steps:

Create a redirect.asp and place it in \Inetpub\wwwroot with this content:

<% 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 %>

In IIS manager, choose properties for the Exchange virtual directory

Choose the Custom Errors tab and double click 403.4, then select URL as the Message Type

In the URL box, type /redirect.asp and choose OK

Users will now be redirected to HTTPS if they mistakenly type HTTP in the URL!
