Rules engine configuration rules

Question

Rules engine configuration rules

Jarosław Bortel 21

Hi guys!

I'm using the Azure Front Door Classic pricing tier and the Rules engine configuration to define routing rules. As the documentation says, there should be a condition operator called "RegEx" -> https://cutt.ly/fCKmieC. Unfortunately, I can't see that on the list. What's the problem? Is it available on the AFD Classic?

If not, so what can I do to configure routing for the request path "users/{userId}/avatar", where "{userId}" is not a const string, but GUID. I've tried to use a wildcard "users/*/avatar", however this solution doesn't seem to work.

Thanks for any suggestions!

Hi

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you are trying to use "Regex" under Rule Engine of classic AFD.

I am able to repo your issue; I do not see the "Regex" operator in the Portal.

I shall check internally and will update you if this is supported in Classic AFD or not.
Kindly allow me some time.

Thanks,
Kapil.

Hi @Jarosław Bortel ,

I just got an update that "Regex" is not supported in classic AFD.
Apologies on the documentation content. I shall work internally to update the relevant documents to reflect this.

Wrt your requirement,

We would require Regex to use "*" and match the pattern.

So, I would suggest you upgrade to Standard/Premium to use Regex operator.

Once again, apologies on the documentation part.

Please let me know should you require additional information on this.

Cheers,
Kapil

Hi anonymous user-MSFT,

thanks for the clarification. I was a little bit confused about what the documentation said and how the AFD really works. Now it's clear.
Upgrading to the Standard/Premium is impossible in this case, so I need to find other way to figure out the issue.

Greetings!

Hi @Jarosław Bortel ,

"Regex" and "NotRegex" operators are not supported under classic AFD Rules Engine.

To make use of the above, we would be required to upgrade to Standard/Premium AFD Plan.

I have created an internal work item to update the document and it should reflect soon.

Thanks,
