I am running a simple HTTP client using sockets to get a web page from a server.
It works perfectly on my Windows XP computer, but when I copy the program over to a linux host, the only response I get from the web server is "HTTP/1.1 400 Bad Request".
I tried recompiling the source on the linux host, but to no avail. (I know, shouldn't have to do this with Java)
Any help is much appreciated. Thank you

SocketAddress sockaddr = new InetSocketAddress(addr, 443);
try {

socket.connect(sockaddr, 2000);
socket.setSoTimeout(2000);
wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF8"));
rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
} catch(IOException e) {
System.out.print(e);
}
wr.write(theReq);
wr.flush();
for(line = rd.readLine();line !=null && line.indexOf("</body>") == -1;line=rd.readLine())
{
System.out.println(line);
}
There is the code for what I am doing... And Yes, I have tried switching the "User-Agent" header to a Firefox/Linux string.
Did I give the right answer, or was it the \n for unix/linux answer?
By the way, go to ftp://ftp.rfc-editor.org/in-notes/rfc2616.txt
That's the text version of the RFC. Look at page 31, section 4.1
They impose CRLF - which means Carriage Return and Line Feed
Also, see:
"HTTP/1.1 defines the sequence CR LF as the end-of-line marker for all
protocol elements except the entity-body (see appendix 19.3 for
tolerant applications). The end-of-line marker within an entity-body
is defined by its associated media type, as described in section 3.7."
