Capture request/response from Azure frontdoor

Question

Is there a way where we can inspect traffic going through Azure front door?, I have a use case where the traffic flows through azure front door to several app services that are behind. Instead of monitoring several app-services below, would like to monitor at front door. I want to collect request/response headers and body for each API transaction and export it to external service, so that the service can monitor things.
I see below blog explaining about AXE custom module which is behind rules engine, could we expect custom-policy plugin/extension support, where these could be supported?

Hi Yashwant

Greetings!

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

Unfortunately, there is no mechanism that you can use to capture request/response headers and body from the Front Door as of now.

Also, the logs will not really help as the information provided by them is totally different from the headers added by the Front Door. Below is the information available in access logs:

Refer: https://learn.microsoft.com/en-us/azure/frontdoor/standard-premium/how-to-logs#access-log

Access logs

Information about every request is logged into the access log. Each access log entry contains the information listed in the following table.
