Internet Explorer 11 returns 408 for ajax POST request RRS feed

  • Question

  • We have a website that makes ajax POST call. Since recently we found that lot of our users are getting 408 for ajax POST. This is not a consistent repro, but we can repro this in IE 11 browser. The ajax call makes an OPTION call and POST call. OPTION call always returns success statue code. But POST calls returns 408. Fiddler shows the POST request body is always empty when erroring out 408 case. Looks like that the call timeout before sending the body. I found several articles online about similar experience in IE 11, but could not find the reason or a solution.  Why is this happening IE11 ? is there a solution for this issue ? 

    Thanks.
