Steps to reproduce

Our web app has started refreshing on a post. It is pretty consistent, about once every five posts. Immediately after our post, we see a request to We blocked this host, but the issue remains. Does not occur on any other browsers, this is a stable existing app.

For what it is worth, the refresh seems to be related to when our page is running in a nested frameset (a frameset that contains another frameset).

When we let the telemetry request go through, it gets a 406 error, and does not return any bytes even though it is returning a content length.

  • Would you be willing to provide us with a fiddler trace so we can look into the 406 response please?

  • Are you able to take a fiddler trace so we can look into this further? We need more information before we can consider this item actionable. Screenshots, reduced cases, fiddler, or wireshark trace - something along those lines will help.

  • Added two Fiddler files. Show same thing. First fiddler was from day of original post, second from today to make sure problem still exists. I did notice a specific patter. The host application is a frameset within a frameset. The refresh, and the Watson call, happen immediately after a POST returns a replacement frameset.

  • Hello,

    The Fiddler files seem to have gone missing somehow - in order for us to investigate further these are crucial. Would you happen to still have the files for re-upload?

    Sorry to be the bearer of bad news. Looking forward to your update.

  • Re-attached the two Fiddler files. Also, I got a message from someone a month or so ago that the problem had been reproduced by Microsoft.

  • Changed Status to “Needs root cause”

  • The Fiddler trace shows werfault doing a request after each repro. This is a strong indication that the page is causing a crash. Do you still repro with the Windows 10 Creators Update (build 15063)?

    If so, can you please file a feedback item through Feedback Hub when you see this? Please let us know the title of the report so that we can look it up on our end.

    Thanks for continuing to work with us to root cause and resolve this issue!

  • I have confirmed that the issue is no longer present in Edge on creator version (40.15063.0.0) and version 38.

    Changed Status from “Needs root cause” to “Not reproducible”

  • Thanks for the validation.
