A question related to Go as "\n" in Go does not mean CR LF --

Is http header requires CR LF as line end?

Perl can handle "\n" automatically for CR LF, but I saw a Perl program ends each http header specifically with CR LF.

Shall I care about doing the same thing for my Go http handling?

This is not a golang question per-se, but a question about HTTP headers. My suggestion is to read up on HTTP headers and their requirements here:

https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html

And concerning inserting an actual carriage return followed by a line feed, you can see how to do that here (hint, know your ASCII characters):

https://golang.org/pkg/fmt/
