Detecting a Secure Port

Written by Eric Smith, Northstar Computer Systems LLC

If you’re running a secure web site with IIS, you can easily verify that the user is viewing a page through a secure port. Just check the HTTP variable called SERVER_PORT to determine how the user is looking at the page. Here’s a snippet of code that checks the port and redirects the user to the secure site if he/she isn’t using port 443 to access the site:
   If Request("SERVER_PORT") <> 443 Then
      Response.Redirect SECURESITE & "adm_login.asp"
      Exit Sub
   End If
