I wrote this HTTP to HTTPS redirection script for a customer so that they were able to leave TCP port 80 open through their firewall to make the transition over to using the Citrix Secure Gateway (CSG) solution a little less confusing for their users. There were a couple fo goals I wanted to achieve with this script:<\/p>\n

    \n
  1. I needed to write a single script that could run from “C:\\Inetpub\\wwwroot” and “C:\\Inetpub\\wwwroot\\Citrix\\XenApp”.<\/li>\n
  2. I didn’t want to hardcode any customer specific information into the script to make it more universal.<\/li>\n<\/ol>\n

    This script has been fully tested with Citrix Web Interface (WI) 5.0.1 and Citrix Secure Gateway (CSG) 3.1, but can easily be adapted for previous versions.<\/p>\n

    Please read the comments within the script so that you will understand\u00a0how\u00a0it’s been\u00a0implemented.<\/p>\n

    Save this script as default.asp<\/p>\n
