I had several people contact me recently about broken Apache installation where the issue was actually with Chrome (I think starting with 43). When a system has IP-based vhosts on 127.0.0.0/8 besides 127.0.0.1 and uses the hostname anything.localhost, Chrome will no longer load those pages. This is their change: https://code.google.com/p/chromium/issues/detail?id=455825
This is not an HTTPD-specific issue, but I could see it being included either in the documentation or as a startup warning if there are vhosts ending in .localhost. Before I start writing/coding, I was wondering whether others think it is worth it? - Y
