I have recently upgraded my JIRA/Confluence datacenter instances to version 8.20.3 and 7.4.14 respectively.
After upgrading, HTTP responses on both have included the keep-alive header, which you can see here (you can check out my public site here: https://support.member.buzz):

This header is technically not allowed in HTTP/2, as you can see here:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Keep-Alive
While most browsers ignore it, some versions of Safari (v13 and older) will not load the page if the header is present. You can see that in action here:

Here are some additional points:
Is there any way of disabling the keep-alive header so that my site will work in Safari (and be HTTP compliant)?
p.s. it seems like if I set the maxKeepAliveRequests option in my server.xml file to 1 it will stop the keep-alive header from being sent - but will that break anything?
