Hello @Christopher Felpel ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you would like to know if there is a way to detect URLs that contain multiple forward slashes in the path portion of the URL processed through Front Door using rule set match conditions.
I discussed this with the Azure Front Door Product Group team and below is their response:
This is not possible in Rules Engine. Multiple slashes at the beginning of the URL are normalized before the condition evaluates, so a rule configured to match multiple slashes at the beginning of the path will not match. Using routes won't work either as we normalize before matching the route. This is unachievable as of today.
If you wish you may leave your feedback in the below forum requesting this feature. All the feedback you share in these forums will be monitored and reviewed by the Microsoft engineering teams responsible for building Azure.
Kindly let us know if the above helps or you need further assistance on this issue.
Please "Accept the answer" if the information helped you. This will help us and others in the community as well.
