From e0ebb7f1727cb1fdcc269f449dfa283ef5729f6d Mon Sep 17 00:00:00 2001 From: Jagan Peddabavi <157447885+Jpeddabavi@users.noreply.github.com> Date: Tue, 1 Sep 2026 17:36:56 -0700 Subject: [PATCH 1/2] Add FAQ about multiple X-Azure-Ref values - question: Why do I see multiple X-Azure-Ref values in my backend application logs when requests pass through Azure Front Door? answer: The X-Azure-Ref value displayed in the client response and Azure Front Door access logs represents the primary request correlation identifier generated by Azure Front Door. Additional X-Azure-Ref values observed only in backend application logs are expected and are internal correlation identifiers generated during request processing within the Azure Front Door platform. These internal identifiers are used by the service for request tracking and diagnostics and don't indicate multiple client requests. --- articles/frontdoor/front-door-faq.yml | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/articles/frontdoor/front-door-faq.yml b/articles/frontdoor/front-door-faq.yml index 3e52e94e2e10..b8d24dbf2544 100644 --- a/articles/frontdoor/front-door-faq.yml +++ b/articles/frontdoor/front-door-faq.yml @@ -142,6 +142,11 @@ sections: answer: | To use Azure Front Door Standard or Azure Front Door (classic), you need a public IP address or a publicly resolvable DNS name.
