IE11 Ajax Aborted After 5 Minutes

Does IE11 automatically abort AJAX requests if it takes too long to get a response? Using Angular4, I'm creating a fairly simple call: 

this.http.post(url, requestJson, options)
    .map((response: Response) => <string>response.json())

But, this runs for a pretty long time on the server before responding. What I'm experiencing is IE is aborting the request after 5 minutes. On Chrome, I don't see the request being aborted.

When the request aborts, I get the error: XMLHttpRequest: Network Error 0x2ef3, Could not complete the operation due to error 00002ef3. which, according to MS's documentation means ERROR_INTERNET_INCORRECT_HANDLE_STATE.

Looking at Wireshark, I'm seeing IE is sending a TCP reset at the same time.

I only experience this behavior talking with our server - the request is not aborted when running the site and server locally.

Is there a way to modify this timeout so that it does not abort? Note: A more long-term solution we'll work towards is modifying the behavior of this request so the request is not hanging for minutes before receiving a response (set up some kind of notification system for when long-running requests are done).

Things I've tried, that have not solved the problem:

You might consider transitioning to Websockets or Long Polling if you are going to have long wait times. This seems like an appropriate application to move the client/server communication to something that is better suited to long delays in communication. I'm not sure why IE11 would behave like this, however, it sounds like you have a long wait and if the server gets loaded down even more at one time this can cause the response time to be further delayed. Is this an option for you?
