Hi, I've just testing the HTTP request packets with line ending "LF"(\n) instead of "CR LF"(\r\n). However, I found that the HFS does not response to client host. Does the HFS can response to this line ending?
Note: In RFC 2616, there is a section to state the tolerance provision about line ending. In Stackoverflow, there is a thread about line ending on HTTP request: http://stackoverflow.com/questions/5757290/http-header-line-break-style

No, it doesn't respond
You can split a request to a new line with OA (LF)
But, request should finish with 0D 0A 0D 0A (CR,LF,CR,LF)
or minimum (CR,CR) works
(LF,LF) wont

You said "HFS can response to this line ending?"
The answer is YES, you can "begin a new line" in the request with LF.
But the "whole request" can not be terminated with LF or LF,LF (as above)

indeed, CR CR works too, LF LF doesn't.
i don't remember anymore why i did so, but i guess the ENTER key is sending a CR, so to support telnet sessions
