Get Orbitz search result with CURL?

[killuagdt]

I am using php 5.3.2 with ISS7. I am currently looking to do get search result from Orbitz. This is what LiveHeader of firefox send me:

/App/SubmitQuickSearch?z=24ad&r=h searchType=air&source=advanced&searchTab=&dpHidden=&tripLength=7&searchMethodHidden=find&expandTravelers=false&WebLogicSession=A2B3ADE3E700AE0EBE74527EE28F1475&orbotHotelSearchTypeKey=+&previousBot=&currentBot=&isBot=true&isBasicDataPersistenceOnly=true&isFlex=&flightType=roundtrip&origin=lax&destination=las&startDate=08%2F30%2F10&useStartCal=true&startTimeType=Depart&startTime=Anytime&endDate=08%2F31%2F10&useEndCal=true&endTimeType=Depart&endTime=Anytime&adults=1&seniors=0&youths=0&children=0&infantsWithoutSeat=0&infantsWithSeat=0&Search.x=true&preferencingType=airline&carrier1=&carrier2=&carrier3=&alliance=&cabinClass=Economy

 

when I try to search a flight from Lax to Las on 30 and 31. I try this code to get the result:

<?php
    $url = "http://www.orbitz.com/App/SubmitQuickSearch?z=24ad&r=h";
    $ch = curl_init(); 
curl_setopt($ch,CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'searchType=air&source=advanced&searchTab=&dpHidden=&tripLength=7&searchMethodHidden=find&expandTravelers=false&WebLogicSession=A2B3ADE3E700AE0EBE74527EE28F1475&orbotHotelSearchTypeKey=+&previousBot=&currentBot=&isBot=true&isBasicDataPersistenceOnly=true&isFlex=&flightType=roundtrip&origin=lax&destination=las&startDate=08%2F30%2F10&useStartCal=true&startTimeType=Depart&startTime=Anytime&endDate=08%2F31%2F10&useEndCal=true&endTimeType=Depart&endTime=Anytime&adults=1&seniors=0&youths=0&children=0&infantsWithoutSeat=0&infantsWithSeat=0&Search.x=true&preferencingType=airline&carrier1=&carrier2=&carrier3=&alliance=&cabinClass=Economy');
    $output = curl_exec($ch);
curl_close($ch);
echo $output;
?>

 

but I received "We’ve noticed there hasn’t been any activity for a while. Please search again for the latest results." error from Orbitz. I can actually see the directing screen before seeing the error. So could you please help me with this problem? I'd really like to know how Bookingbuddy does this. Thank you very much for your help.
