I think it might have been a urlencode error on my part.

Not that huge. About 400 characters.

A copy of a GET string below

http://www.blahbh.com/zippo/Search.ASP?WCI=AddToPortFolio%26PAGE%3D1%26DEL%3
D%26PropertyID%3D00595876%26GTYP%3D0%26ID%3D0009185%26PER%3D10%26XSLT%3D-1%2
6GID%3D580%26SQL%3D2+AND+Property.EstateAgentID+%3D+580+AND+%28Property.Inst
ructionLevel+%3C+2%29+AND+%28%28Property.Price+%2A+CurrencyConversion.Value%
29+%3C%3D+99000000+AND+%28Property.Price+%2A+CurrencyConversion.Value%29+%3E
%3D+0%29%29+AND+Property.Price+%3C%3D+300000

I think it must be a misunderstanding on my part about using curl(). If you
have a moment, and don't mind, could you take a look through this and look
for any screamers?

$query .= "&PAGE=1";
$query .= "&DEL=";
$query .= "&PropertyID=00595876";
$query .= "&GTYP=0";
$query .= "&ID=0000000";
$query .= "&PER=10";
$query .= "&XSLT=-1";
$query .= "&GID=400";
$query .= "&SQL=2 AND Property.EstateAgentID = 580 AND
(Property.InstructionLevel < 2) AND ((Property.Price *
CurrencyConversion.Value) <= 99000000 AND (Property.Price *
CurrencyConversion.Value) >= 0)) AND Property.Price <= 300000";

// create a new curl resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_REFERER, "http://www.blahbl.com/
zippo/Search.ASP?WCI=AddToPortFolio");
curl_setopt($ch, CURLOPT_POSTFIELDS, urlencode($dezrez_query));
// return curl as a string

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$login_contents = curl_exec($ch);
print $login_contents;
// close curl resource
curl_close($ch);
