Thank you for your support of Alibaba Cloud. Due to product strategy adjustments, the DCDN product WAF real-time log function will adjust the log format of the URI field at 00:00:00 on June 2, 2026. The value of the "URI" field in WAF real-time logs will be changed from the previously recorded Tengine-normalized form to the original URI form before normalization (for example: the currently recorded / will be changed to /env;/../). This change will not affect your online business, and will only affect the URI field format in the real-time logs pushed to you. The risk is low, please be informed.

This change has no API impact.

If your online system relies on the URI field of WAF real-time logs, it is recommended that you complete the adaptation of the field format before the upgrade date to avoid any impact on your service. If you have any questions, please submit a ticket for processing.
