The only way to make an SSL connection through a sideband call is to point your sideband call at a local VIP that applies server side SSL. So

 

  • A user makes a request to my web app via LTM
  • A request comes on LTM and hit an iRule
  • The iRule establishes a non-SSL connection to a local VIP that load balances to CRED on Internet and applies a server SSL profile to do HTTPS to CRED, on port 443.
  • After connection is established, the iRule makes a request like "GET /mypage/myindex2.html HTTP/1.0\r\n\r\n"
  • The iRule receives data and closes the connection to CRED
  • The iRule makes a decision if a user is allowed to see requested url.
  • The user gets requested data or his session is rejected/forwarded to another page.
