X-MS-ApplicationGuard-Initiated header is not present in any request

Copper Contributor

Hi there,

we have enabled the gpo ( https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#applicationguardtrafficidentific... ) and it is active when we check with rsop and i see it under edge://policy in the local edge (chromium) and the edge in micro vm


But when i check the traffic with fiddler or any other public http header checker, there is no header "X-MS-ApplicationGuard-Initiated", therefor our proxy cant react on this header....while user authentication is not possible in the appguard container we are stuck on this point.


Anyone a idea whats wrong here? Test Environment is with 100, 101 (current builds) and 102 (dev build)...any version seems to behave the same.


Any ideas on this? Did i miss something?
