-> **Note**
+> [!CAUTION]
 > Please note that when you disable HTTP probing (either by setting `DSLIM_HTTP_PROBE_OFF` to `true` or `DSLIM_HTTP_PROBE` to `false`), it will effectively modify the behavior of the continue mode (if the `DSLIM_CONTINUE_AFTER` value is undefined) by imposing a timeout of **1** second. This adjustment occurs because, by default, when HTTP probes are disabled, the Slim's behavior will switch to '**enter**' mode — and there is no way to interact with the temporary container created by Slim within the GitHub Action runner.
