Hi everybody,

I am trying to get a list of result pages from one asp site.

I found it extrange about how it works, and I'd like to ask for some help if
you don't mind.

How the site works:

You get a result page, and then any of the result links 1 2 3 4 ... next 10
link the same page.

So I found it is a form with some normal and hidden fields.

What happens:

I am not able to get any page a part from the first one.

What I did:

I've simulated manually the behavior of the script and checked the
sourcecode of the page.

I have here one VIEWSTATE wich is always the same. I've tried many times.

After that:

I run my script, but the VIEWSTATE I got is different. I suppose it is the
problem.

The code to get the page:

# Define main url

$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; es; rv:1.4)
Gecko/20030624 Netscape/7.1 (ax)";

            $cookie_file_path = "tcookies.txt";

            $url = $domain;

            $n=0;

# Cookies generation

            while($n<5) {

                        # Defined parameters

                        $ch = curl_init();

                        curl_setopt($ch, CURLOPT_URL, $url);

                        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

                        curl_setopt($ch, CURLOPT_USERAGENT, $agent);

                        curl_setopt($ch, CURLOPT_COOKIEFILE,
$cookie_file_path);

                        curl_setopt($ch, CURLOPT_COOKIEJAR,
$cookie_file_path);

                        $result = curl_exec ($ch);

                        curl_close ($ch);

                        # Simulate user behavior

                        if ($n==0) $url= $domain .
"/busqDirectas/busquedas.html";

                        if ($n==1) $url= $domain .
"/busqDirectas/comprar/comprar_inmuebles.html";

                        if ($n==2) $url= $domain .
"/busqDirectas/comprar/Piso_Apartamento/comprar_inmuebles_Piso_Apartamento.h
tml";

                        if ($n==3) $url= $domain .
"/busq/resultados.aspx?CodParam=IdTipoInmueble.2_IdTipoOferta.2_idProvincia.
43";

                        $n++;

            }

            # Get special characters of spanish

            $result=utf8_decode($result);

            # Show page to check __VIEWSTATE

echo $result;

            die();

Domain:

If anyone wants to chek it, domain is www.f#o#t#o$c
<http://www.f/#o#t#o$c&a&s&a.es> &a&s&a.es - Please remove # and &. Is
important from me to hide this url from search engines.

Next code:

After that code I've got the one to get the form, but I think my problem is
here, to get this page with the original VIEWSTATE.

There's some things I can't understand as special characters, binary mode,
etc, of this string of VIEWSTATE.

May be someone could help me.

Thanks in advance,

Sam
