Should be YES? https://docs.microsoft.com/en-us/azure/app-service/deploy-staging-slots You can also customize the warm-up behavior with one or both of the following app settings: WEBSITE_SWAP_WARMUP_PING_PATH: The path to ping to warm up your site. Add this app setting by specifying a custom path that begins with a slash as the value. An example is /statuscheck. The default value is /. WEBSITE_SWAP_WARMUP_PING_STATUSES: Valid HTTP response codes for the warm-up operation. Add this app setting with a comma-separated list of HTTP codes. An example is 200,202 . If the returned status code isn't in the list, the warmup and swap operations are stopped. By default, all response codes are valid. WEBSITE_WARMUP_PATH: A relative path on the site that should be pinged whenever the site restarts (not only during slot swaps). Example values include /statuscheck or the root path, /.

I agree. For ASP.NET and ASP.NET Core developers, setting app settings in App Service are like setting them in <appSettings> in Web.config or appsettings.json, but the values in App Service override the ones in Web.config or appsettings.json. https://docs.microsoft.com/en-us/azure/app-service/configure-common#configure-app-settings

Question is not only for warm-up but also to execute custom script. So Answer No is correct.

it states that a new method called statuscheck is added to the application that executes these scripts. if you add the path to /statuscheck in WEBSITE_SWAP_WARMUP_PING_PATH the application executes the scripts

The answer is right to be marked as 'No' as the warm up is done correctly but the web config part is not mentioned i.e, AppInitialization.

Copilot AI says No: The solution does not meet the goal. Updating the app with a method named statuscheck to run the scripts and setting the WEBSITE_SWAP_WARMUP_PING_PATH and WEBSITE_SWAP_WARMUP_PING_STATUSES app settings are not sufficient to ensure that scripts run and resources are available before a swap operation occurs. These settings are used to configure the health check for the swap operation, which determines whether the source slot is ready to be swapped with the target slot. However, the health check does not guarantee that the scripts run and resources are available, as it only verifies that the app responds to HTTP requests with the expected status codes.

Quote "You need to ensure that scripts run and resources are available before a swap operation occurs." Note from Microsoft "The <applicationInitialization> configuration element is part of each app start-up, whereas the two warm-up behavior app settings apply only to slot swaps." conclusion: for this case where swap is concerned, The proposed solution in the question with appsettings WEBSITE_SWAP_WARMUP_PING_PATH and WEBSITE_SWAP_WARMUP_PING_STATUSES is correct. Hence answer B. Yes.

Should be YES The <applicationInitialization> configuration element is part of each app start-up, whereas the two warm-up behavior app settings apply only to slot swaps. WEBSITE_SWAP_WARMUP_PING_PATH: The path to ping over HTTP to warm up your site. Add this app setting by specifying a custom path that begins with a slash as the value. An example is /statuscheck. The default value is /. WEBSITE_SWAP_WARMUP_PING_STATUSES: Valid HTTP response codes for the warm-up operation. Add this app setting with a comma-separated list of HTTP codes. An example is 200,202 . If the returned status code isn't in the list, the warmup and swap operations are stopped. By default, all response codes are valid.

Answer is NO. While this solution may work put on your MS thinking hat because modifications to the app should not be necessary when there are other ways to get this to work with no app modifications.

Surely it's yes? You can customize the warm-up behavior with one or both of the following app settings: WEBSITE_SWAP_WARMUP_PING_PATH: The path to ping to warm up your site. Add this app setting by specifying a custom path that begins with a slash as the value. An example is /statuscheck. The default value is /.
