sockets

[123321a]

Socket connects successfully a lot of main urls but some are lost I was trying to connect for example Amazon.com but the connection is refused I don{t Know how to configure a client to connect all urls.
Tnanks in advanced.....

Was the connection refused, or did it timeout? If it was refused, then your socket did not connect successfully.

Are you writing your own client? Or are you using a web browser and getting timeouts on some of the links?

I am writing my own client, I configure each step and unsuccessfully step return a message the connection is unseccessfully because the client return an empty content specifically from Amazon using a POST method; the next is the client:

socket(SERVER,AF_INET,SOCK_STREAM,getprotobyname('tcp'));

$iaddr = inet_aton($host) || return(700,"Invalid Host: $host"
$paddr = sockaddr_in(80, $iaddr) || return(700,"Invalid paddr: $host"

socket(SOCK, AF_INET, SOCK_STREAM, $proto) || return (700,"socket error: $!"
connect(SOCK, $paddr) || return (400,"connect error: $!"
select(SOCK);$|=1;
select(STDOUT);

print SOCK "POST $request HTTP/1.0\n",'Host: ',$host,"\n";
print SOCK "Content-Type: application/x-

http://www-form-urlencoded\n";

print SOCK "Content-Length: $len\n\n";
print SOCK "$vars\n\n";

while (defined($line = <SOCK>)) {
my $now = time;
$diff = ($now-$start);
if( $diff >= $timeout ) { return(600,&quot;Timeout&quot; }
$header .= $line;
}
return(500,&quot;Connection refused!&quot unless $header;
close (SOCK) || return( 700,&quot;close error: $!&quot; );

This is what I get when I do a query on their site. Of course some of this is browser dependant, but they may require some of fields, like Referer, Pragma, Cache-control, Cookie, url, and many of the Accept statements. Otherwise your code looks OK as far as I can tell, but I am far from a programmer, even if it is just PERL.

I'd try your queries manually using telnet with differing option sets before I assumed the code was bad.
