The shopping cart emptying at checkout indicates that requests from the same client are being load-balanced to different pool members, causing loss of session-specific state stored on the originating server. Configuring a persistence profile on the virtual server ensures that all requests from a given client are consistently directed to the same pool member for the duration of the session, preserving cart data through checkout. Client SSL profiles handle TLS termination, HTTP profiles manage HTTP protocol behavior, and OneConnect profiles optimize backend TCP connection reuse — none of these provide client-to-server session affinity.
