       - question: |
           How does the container warmup request work?
         answer: |
-          When Azure App Services starts your container, the warmup request sends an HTTP request to the [/robots933456.txt](/azure/app-service/configure-custom-container?pivots=container-linux#robots933456-in-logs) endpoint of your application. This is simply a dummy endpoint, but your application needs to reply with any status code (including 5xx). If your application logic doesn't reply with any HTTP status code to nonexistent endpoints, the warmup request can't receive a response and it perpetually restarts your container.
-          The warmup endpoint path and the status codes that consider the site warmed-up can be customized from the default behavior by setting the [WEBSITE_WARMUP_PATH](/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet#app-environment) and [WEBSITE_WARMUP_STATUSES](/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet#app-environment) application settings.
-          The warmup request also might fail due to port misconfiguration.

       - question: |
           Is it possible to increase the container warmup request timeout?
         answer:
           The warmup request by default fails after waiting 240 seconds for a reply from the container. You may increase the container warmup request timeout by adding the application setting `WEBSITES_CONTAINER_START_TIME_LIMIT` with a value between 240 and 1800 seconds.
