Steps to reproduce

In our website, we try to access a url [ajax] of another domain from within an iFrame. OPTIONS is being sent to verify whether to allow or not.

Randomly these OPTIONS call take huge time to get the response and some comes in milliseconds. This work fine in all modern browsers even in IE 11 but not in EDGE.

Attached some screenshots which explains the behaviour.

  • Its kinda urgent for our company as we have public release next week, where edge users are facing problem. It would be great if some technical person look at this sooner.

  • Hi Venkatakrishnan,

    I will look at it today and let you know.

  • Ventaktakrishnan,

    Can you send your ajax code for the request you believe is causing the issue?

    Also, can you provide the Windows/Edge version you are using? (Go to start menu, type “winver” in
    search box and then press Enter)

    Thank you

  • Steven K,

    Thanks for the response.

    1. The issue was noticed in the windows 10 systems, where automatic updates are enabled and having latest versions.
    2. Important Note: This started happening very recently, as couple of weeks back we did not notice any issue in the EDGE. Any recent updates ?
    3. As an immediate fix we made some code changes to avoid any CORS and no issues now noticed in EDGE, as we are nearing a public release. But this resulted in our proposed architecture to be changed.
    4. Attached a javascript which explains how we do a AJAX call.
