--- Comment #3 from Mark Thomas <ma...@apache.org> ---
This stricter parsing was introduced as part of the fix for CVE-2020-1935.

Because the fix was in response to a security issue, that makes it a lot less
likely the current behaviour will be changed. 

I'll note that both RFC 7230 and RFC 2616 state that recipients MAY treat
single LR as a line terminator. That makes the behaviour entirely optional and
Tomcat is still fully HTTP spec compliant by opting to reject requests that use
LF as the line terminator.

I need to look into the details of that vulnerability to see if there are any
options to relax the current behaviour without re-introducing a security
concern.
