Until you get to the Generated Cert for the SSL webserver.
IOW something like:
CA-Cert --> Intermediate CA-Cert --> Chained CA-Cert --> Your Cert
Whoever its generated by (like GeoTrust or GoDaddy) will have a Cert Chain or Intermediate for you to put on the load balancer. Usually the Load Balancer needs to have the reference Intermediate Cert available to encrypt properly.
I used Squid as an SSL Accelerator and it requires the Actual Cert, they Cert Key and the Intermediate CA-Cert to encrpyt the data properly.
