Yes, but when developing a server-side CGI script that's returning HTML 
with headers,
you're supposed to always use '\r\n' no matter
what platforms the browsers or the server run on.  It's part of some 
specification I'd guess.

I by no means claim to be an expert at web development.
However, I wrote a few simple CGI scripts, and when you're making a header,
it goes something like this:

Content-type: text/plain\r\n
\r\n
\r\n
<html>\r\n
    <head>\r\n
        <title> hello </title>\r\n
    </head>\r\n
    <body>\r\n
        Hi\r\n
    </body>\r\n
</html>\r\n

You need those two extra returns so that the browser knows it's done 
reading the header
and it should start decoding the html code.
That's all I was referring to.
I don't know if you are supposed to use \r\n always or just in the 
header section,
but I bet browsers would handle either case just fine.

That's just my opinion on all this stuff.
Use \n if it works, I guess.
If you think I might be right, investigate further.
