Newbie:HTTP Post thru SOCKETS got this reply

[Serialmouse]

Man, I used a function called PostToHost which i got from here, but this is the reply I got. The URL needed a POST with two variables, I used the function PostToHost to send the variables but this is what the server replied:

HTTP/1.1 100 Continue Server: Microsoft-IIS/5.0 Date: Tue, 01 Apr 2003 08:44:08 GMT HTTP/1.1 200 OK Server: Microsoft-IIS/5.0 Date: Tue, 01 Apr 2003 08:44:08 GMT Connection: close Set-Cookie: ASP.NET_SessionId=v4uxj355mztomk452cd1duj3; path=/ Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 304 Exception Error-2: System.ArgumentOutOfRangeException: Index and length must refer to a location within the string. Parameter name: length at System.String.Substring(Int32 startIndex, Int32 length) at WebPush.WebForm1.Page_Load(Object sender, EventArgs e) in C:\OMI\WebPush\Push.aspx.vb:line 128

Man, have to solve this fast. Deadline is fast approaching.
Function call was:
PostToHost("some.ip.address","/directory1/recipient.asp","variable1={$variable[$i]}&Webpage=http://some.domain.com/v3/messagebuilder.php?userid=$userid&recordid={$recordid[$i]}");

Function was :

function PostToHost($host, $path, $data_to_send)
{
$fp = fsockopen($host,80);
fputs($fp, "POST $path HTTP/1.1\n");
fputs($fp, "Host: $host\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
fputs($fp, "Content-length: ".strlen($data_to_send)."\n");
fputs($fp, "Connection: close\n\n");
fputs($fp, $data_to_send);
while(!feof($fp))
{

echo fgets($fp, 128);

}
fclose($fp);
}

please help me guys. Help would be great... Thanks a lot!!!

Well, spacing that http response out a bit better it looks more like:

HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Tue, 01 Apr 2003 08:44:08 GMT
Connection: close
Set-Cookie: ASP.NET_SessionId=v4uxj355mztomk452cd1duj3; path=/
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 304

Exception Error-2:
System.ArgumentOutOfRangeException:
Index and length must refer to a location within the string.
Parameter name: length
	at System.String.Substring(Int32 startIndex, Int32 length)
	at WebPush.WebForm1.Page_Load(Object sender, EventArgs e)
in C:\OMI\WebPush\Push.aspx.vb:line 128

Which says that the error occurred in the page you're posting to (the Substring() method got a bad length from somewhere when like 128 of Push.aspx.vb was run).

Can't see anything wrong on the PHP end, except that

variable1={$variable[$i]}&Webpage=http://some.domain.com/v3/messagebuilder.php?userid=$userid&recordid={$recordid[$i]}

is broken (because the value for Webpage contains characters that have a special meaning in URLs).

Assuming that there are only two variables you're sending, "variable1", which contains the $variable[$i], and "Webpage", which contains the rest:

PostToHost("some.ip.address", "/directory1/recipient.asp",
	"variable1={$variable[$i]}&Webpage=".urlencode("http://some.domain.com/v3/messagebuilder.php?userid=$userid&recordid={$recordid[$i]}")
);
