replace http:// to https:// problems

Does the application actually include the :80 port number in the Location header value? If so, you'd need to use an iRule, I think:

 
   when HTTP_RESPONSE {  
    
      Check if server response is a redirect  
     if { [HTTP::header is_redirect]} {  
    
         Log original and updated values  
        log local0. "Original Location header value: [HTTP::header value Location],\  
           updated: [string map -nocase "http:// https:// :80/ /" [HTTP::header value Location]]"  
    
         Do the update, replacing http:// with https:// and  :80/ with / 
        HTTP::header replace Location \  
           [string map -nocase "http:// https:// :80/ /" [HTTP::header value Location]]  
     }  
  }  
 

If it doesn't include the port, you could use a custom HTTP profile with rewrite redirects enabled.
