Question 95

An LTM Specialist is troubleshooting a problem on an eCommerce website. The user browses the online store using port 80, adding items to the shopping cart.

The user then clicks the "Checkout" button on the site, which redirects the user to port 443 for the checkout process. Suddenly, the user's shopping cart is shown as empty. The shopping cart data is stored in memory on the server, and the default source address persistence profile is used on both virtual servers.

How should the LTM Specialist resolve this issue?

    Correct Answer: D

    When a user switches from HTTP (port 80) to HTTPS (port 443), maintaining session persistence is crucial to ensure continuity of the user's experience, such as keeping items in the shopping cart. The 'Match Across Services' feature in a custom persistence profile allows persistence records to be shared across different virtual servers, making sure the session information is consistent and the user is directed to the same server. This would resolve the issue of the empty shopping cart when transitioning from browsing (port 80) to checkout (port 443).

Discussion
adrguimOption: D

A typical use of the Match Across Services feature is for combined HTTP/HTTPS support for the same site. Commerce sites are typically configured to allow customers to view and select merchandise using HTTP, but then the site switches to HTTPS when the customer begins the checkout process. The Match Across Services option is useful in this configuration as it allows the session information to be shared between the virtual servers and ensures that the client is directed to the same pool member.
