2171	Nginx causing missing body content data since v1.19.1	breisig@…		"We are running puma + latest ruby on rails behind nginx (via proxy_pass). We have been running v1.18.0 and we recently upgraded to v1.20.0 and noticed nginx is causing missing characters. Like as if the buffer disconnects abit early.

Example. When I view the page source output using nginx v1.18.0, I see the *propery* output and the end of the stream.

-------
<button name=""button"" type=""button"" title=""Yes, I accept"" class=""button_base inverted no_wrap"" id=""btn_cookie"">Yes, I accept</button>
</div>
</div>

</body>
</html>
-------

But in v1.20.0, the page source is missing data.

-------
<button name=""button"" type=""button"" title=""Yes, I accept"" class=""button_base inverted no_wrap"" id=""btn_cookie"">Yes, I accept</button>
</div>
</div>

</
-------


It looks like the closing </body></html> tags are missing from the page. I have compiled nginx versions from 1.20.0 down to 1.19.0 and noticed that it started breaking in nginx 1.19.1. So something between 1.19.0 and 1.19.1 broke nginx. This is critical to fix.
