+### Enable Advanced Debug Mode Dynamically
+
+The advanced debug mode can be enabled dynamically by a single request and
turned off automatically when the request ends.
+
+Example:
+
+```yaml
+http_filter:
+ enable: true # Enable/Disable Advanced Debug Mode Dynamically
+ enable_header_name: X-APISIX-Dynamic-Debug # Trace for the request with this
header
+......
+#END
+```
+
+Dynamically enable advanced debugging mode, example:
+
+```shell
+curl 127.0.0.1:9090/hello --header 'X-APISIX-Dynamic-Debug: foo'
+```
+
+Notice: Dynamic advanced debug mode cannot hook the `apisix.http_access_phase`
module (because the request enters the `apisix.http_access_phase` module before
it determines whether advanced debug mode is dynamically enabled).
