I’m using Azure AD B2C with a custom policy for authentication and need to handle peak burst scenarios effectively.
During high-traffic events, such as promotions, I want to manage session thresholds to prevent system overload.

Objective:

• Implement a session check during user login attempts.
• Monitor the current session count using Azure AD B2C logs.
• Redirect users to a “Sorry, Try Later” page if the session count exceeds 10,000 user session.

My questions:

1. How can I monitor the current session count using Azure AD B2C logs?
2. What is the best way to check if the session count exceeds 10,000 during a user login attempt?
3. How can I implement the redirection to a “Sorry, Try Later” page when the threshold is exceeded?
   Any guidance or examples would be greatly appreciated!
