-----------------------------------

Even though this is likely a bug, seeing that it's intentional, I suggest we land this for 7.0.0.

> If an HTTP request header terminates one of the fields with just a line feed ATS will parse it as if the header terminated at the end of the previous line. I think I understand why this was done but in my opinion that is obsolete and ATS should instead generate a parse error. Such a request in my reading clearly violates the HTTP specification and should therefore generate a parse error. Another option is to treat the line feed as a proper line terminator which, while I think would be better than the current behavior would still be wrong. General usage has advanced sufficiently that ATS should require properly formatted request headers.
