IE11 CORS Preflight aborted RRS feed

  • Question

  • Hello,

    I am struggling with a CORS issue. With Chrome and firefox everything is fine but with IE the preflight is aborted.

    You can reproduce the problem with plunker https://plnkr.co/edit/qcfl8sDG4ibxMW9eFJLW?p=preview

    The normal behaviour should be a call to option following by a get. The GET will returns 401 as the token is not provided in plunker. 

    Normal behaviour with chrome

    OPTIONS /quote/v1.0/Q123 HTTP/1.1  HTTP/1.1 200
    GET /quote/v1.0/Q123 HTTP/1.1 HTTP/1.1 401

     Problem with IE11

    URL Protocol Method Result Type Received Taken Initiator Wait‎‎ Start‎‎ Request‎‎ Response‎‎ Cache read‎‎ Gap‎‎
    https://api-uat.champ.aero/quote/v1.0/Q123 HTTPS (Aborted) 0 B < 1 ms CORS Preflight 282908 0 0 0 0 46

    Any idea ?

  • Hi Rob,

    Thank you for your reply. I also reported my issue on stack overflow. Some people are referring a bug in IE11 https://connect.microsoft.com/IE/feedback/details/1028302/ie11-cors-preflight-request-is-aborted-when-server-requests-client-tls-certificate

    But apparently microsoft connect is not working anymore.
