Hello,
Hello,
I created a script for checking HTTP like below:
use strict;
use IO::Socket;
my $host = shift || '127.0.0.1';
my $port = shift || 80;
my $sock=IO::Socket::INET->new(PeerAddr => $host,
PeerPort => $port,
Proto => 'tcp');
unless (defined $sock) {
exit -1;
}
print $sock "GET / HTTP/1.0\n\n";
...
For above line, if the remote server OS is Windows, should I send "GET
/ HTTP/1.0\r\n\r\n" instead of "GET / HTTP/1.0\n\n" ?
If yes, then the check script seems not useful, because before each
checking, we must know what the OS of remote server is.
Please give the suggestion.
According to RFC 2616 (http://www.rfc-editor.org/rfc/rfc2616.txt) the
end-of-line marker is CRLF which is not dependent on the OS.
AFAIK most TCP protocols use this end-of-line marker.
