Request Redirection - Domain Change?

Question

Hi, I am trying to create a vanity URL that redirects domain, virtual directory and port as follows; 
 Virtual Webserver 
 
 Interface: Internet 
 Type: Encrypted (HTTPS) & Redirect 
 Certificate: Commercial Wildcard 
 Domains: alpha.domain.com 
 No Real Webserver 
 No Firewall Profile 
 Advanced: Defaults 
 
 Site Path Routing: 
 
 Path: /appfolder 
 Reverse Authentication: No Profile 
 Real Web Servers: Web App 
 No Access Control 
 Advanced: Defaults 
 
 Request Redirection: 
 
 Source
 
 Path: /

Target
 
 Host: beta.domain.com 
 Path: /appfolder 
 Protocol: Encrypted (HTTPS) 
 Port: 8000

Reponse Code: 301 
 
 My aim is for the user to enter alpha .domain.com and get redirected to https:// beta .domain.com:8000/appfolder 
 Instead, the browser is requesting https:// alpha .domain.com:8000/appfolder 
 The web app has clickjack protection that accepts only the expected host header so this won't work. 
 Am I doing something wrong or is what I want not possible?

Several options. 
 First website continues to exist, with a single page containing the redirect cimmand.  WAF is optional 
 WAF offers old website as virtial webserver, connects to new website as real webserver.  You neeef a certificate for the old name as well as the new one. 
 Use a wildcard or multi-SAN certificate and publish the single site under both DNS names. 
 What will not work: 
 NAT can translate the IP address and port, but will fail with cerificate errors.   NAT cannot change URL, and cannot redirecct http to https.  URL used must match the certificate returned from the server.
