HTTPS for CCA Interaction manager?

Question

our configuration uses https connectivity for clients using interaction manager. Therefore, http ports have been disabled. When I login to interaction manager at https://<hostname>/cca/, i'm presented with the login screen.
Upon login, the cca app begins launching and downloading jar files from the server as needed. When it tried to download these jar files, somehow the protocol used is http instead of https.
We suspect that the cause is cca/download.jsp (in the web archive cca.war). Our environment uses Weblogic and Sun One web Server. Sun One Web Server actually receives all client requests and proxies them to Weblogic (cca).
In cca/download.jsp, the following code exists. I believe that cca is unable to guess the protocol and defaults to http. We need the default to be https.
String protocol = null;
try{
protocol = request.getProtocol();
//We don't need the version information, split it away
String[] arrProtocol = protocol.split("/");
protocol = arrProtocol[0].toLowerCase();
catch(Exception e){
System.out.println("Errror occurred: " + e);
//If there is any error in getting the correct protocol, we could still use http^M
//to install and it would work
protocol = "http";
}

We used external SSL devices to handle HTTPs. The F5 Big IP load balancers can sit in front of CCA and they can be configured to off load the SSL from the CCA web servers.
