Severity: 4-Minor


When a request is blocked due to "Cookie not RFC-compliant' violation, the description field in the request log details is shown as "N/A" instead of having the description (for example "Invalid equal sign preceding cookie name" or "Invalid space in cookie name").


The description is empty and we can't know what is the problem with the request.


The violation is blocked due to "Cookie not RFC-compliant" violation and we are looking at the request log details.
