Newlines in HTTP

The HTTP 1.1 standard says that newlines are CRLF. However wget, lynx, and firefox, all accepts a response in UNIX format.

Is it acceptable for a HTTP parser to simply skip all carriage returns in the header?

>Solution :

From RFC 9112, section 2.2:

Although the line terminator for the start-line and fields is the
sequence CRLF, a recipient MAY recognize a single LF as a line
terminator and ignore any preceding CR.

If you were to build a recipient (client or server), it would be RFC compliant to parse requests that only send an LF as line terminator.
