Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36 Steps to reproduce the problem: 1. Browse to https://repro-isag.intermall.de/cad-plotservice.html (Note: this is a testserver - might be password protected/unavailable after this issue has been solved) 2. Click on the left Image ("FARBPLOTS") to upload a file 3. upload the attached .pdf file 3. Wait... What is the expected behavior? File upload should finish and show the files in a table below the uploader. What went wrong? File upload stops between 1 and 99%, the request stays as 'pending', all further requests to the website timeout. Did this work before? N/A Chrome version: 55.0.2883.87 Channel: stable OS Version: 6.1 (Windows 7, Windows Server 2008 R2) Flash Version: Shockwave Flash 24.0 r0 the same problem occurs with opera, vivaldi, but works fine with any other (non-webkit) browser (firefox, IE). This works with chrome/opera/vivaldi if you do the same on the non-ssl page ( http://repro-isag.intermall.de/cad-plotservice.html ). Also this problem has some similarities to https://bugs.webkit.org/show_bug.cgi?id=5760 (very small files work - tested with files < 10kb, disabling keepalive didnt help though). Server uses php 7.0.10 and apache/2.4.18 (FreeBSD)

Disabling HTTP2 in Apache seems to work - you can't reproduce the problem now anymore on the linked page. Though this is not a real solution it is sufficient for our needs, and probably points the error to server configuration and not the browser - though its weird that firefox and ie work flawlessly while chrome/opera/vivaldi seem to cause problems. So you can close this i guess...
