cURL, frames & letitbit.net: Could you help me please?

Question

I have written a script for Letitbit.net. With help of cURL I can get to the page where after 60 secs is to appear the link to the file I want to download. That page uses frames... If I get to the page via a browser, the sourse code looks just like this:

<frameset rows="125,70,*" frameborder="no" border="0" framespacing="0">
<frame src="http://letitbit.net/tmpl/tmpl_frame_topad.php" name="mainFrame" scrolling="No" noresize="noresize" id="mainFrame" title="topFrame" />
  <frame src="http://letitbit.net/tmpl/tmpl_frame_top.php?link=http://r3.letitbit.net/download100/7930.7504ba9eaf495fe8945741a1d3_tybujkhg9e17poo/719028/letitbit.net/___2.7z" name="topFrame" scrolling="No" noresize="noresize" id="topFrame" title="topFrame" />
  <frame src="http://letitbit.net/wawname/letitbit.html" name="mainFrame" id="mainFrame" title="mainFrame" />
</frameset>

But when this is done with my PHP script I get this:

<frameset rows="125,70,*" frameborder="no" border="0" framespacing="0">
<frame src="http://letitbit.net/tmpl/tmpl_frame_topad.php" name="mainFrame" scrolling="No" noresize="noresize" id="mainFrame" title="topFrame" />
  <frame src="http://letitbit.net/tmpl/tmpl_frame_top.php?link=" name="topFrame" scrolling="No" noresize="noresize" id="topFrame" title="topFrame" />
  <frame src="http://letitbit.net/wawname/letitbit.html" name="mainFrame" id="mainFrame" title="mainFrame" />
</frameset>

That is where the actual link is missing. (http://r3.letitbit.net/download100/7930.7504ba9eaf495fe8945741a1d3%5Ftybujkhg9e17poo/719028/letitbit.net/%5F%5F%5F2.7z) What's the problem? Could you please give me some clues?

Answer 1

Look at the JavaScript. it might be writing the link dynamically.

Answer 2

Make sure you're sending all cookies and POST arguments to /download3.php

Notable cookies:

advm
coutnry
mgid
pop
ref_full
ref_site
reserv

Notable POST'ed form arguments:

uid
md5crypt
cap
frameset
uid2
uid5
uid
name
pin
realuid
realname
host
ssserver
sssize
optiondir
fix

Failure to send correct values for any of those could conceivably cause the problem you're seeing.

Answer 3

@Frank Farmer: bro, there was the frameset argument missed in my request, but where did you find the fix cookie?

This is all the form has:

<form action="http://letitbit.net/download3.php" method="post" id="dvifree">
   <input type="hidden" name="uid" value="2245376a60aebc53938549a0c4716a9d" />
   <input type="hidden" name="md5crypt" value="aHR0cDovL3I1NC5sZXRpdGJpdC5uZXQvZG93bmxvYWQ1MC8yYjQ0NmUzNTUxODVfbDFxa293cDcxOTMzdDd2MS83MTk2MjgvVmVyeS1CaWctQ2xpdC5yYXJ8NzE5NjI4fDI1ZjI3Mjc3NTVhMDRkOHxWZXJ5X0JpZ19DbGl0LnJhcnxsZXRpdGJpdC5uZXR8NA==" />
   <div class="dlBlock">
   <div class="title">
   <div class="top"></div>
   <!--<h4></h4>-->
   <span style="font-size:16px">Download file&nbsp;
With the <b>expectation</b> minute and <b> viewing </b> Site  <b style="color:#FFFFFF;"></b></span>

   </div>
   <div class="cont c2" align="center">
   <br /><br />
   <img src='http://letitbit.net/cap.php?jpg=2b446e355185.jpg' border='0'>
   <input type='text' maxlength='6' size='10' name='cap' class='name-login' style='width:80px; font-size:18px;background: url(http://images.letitbit.net/image/inpText_h25_bg.gif) top repeat-x; border: #838383 1px solid;'>
   <input name="frameset" type="submit" class="newb" onMouseOver="this.className='newb2'" onMouseOut="this.className='newb'" value='Download file' />
   <input type="hidden" name="uid2" value="2b446e355185" />
    <br>
        Enter the symbols you see in the  images     </div>

   <center><br><a href="http://bonusfile.com/comments.php?oid=Very-Big-Clit.rar"&gt;&lt;/a&gt;&lt;/center&gt;
   </div>
   <input type="hidden" name="uid5" value="2245376a60aebc53938549a0c4716a9d" />
   <input type="hidden" name="uid" value="2b446e355185" />
   <input type="hidden" name="name" value="Very-Big-Clit.rar" />
   <input type="hidden" name="pin" value="719628" />
   <input type="hidden" name="realuid" value="25f2727755a04d8" />
   <input type="hidden" name="realname" value="Very_Big_Clit.rar" />
   <input type="hidden" name="host" value="letitbit.net" />

   <input type="hidden" name="ssserver" value="r54" />
   <input type="hidden" name="sssize" value="5526201" />
   <input type="hidden" name="optiondir" value="4" />
</form>

Also, this may be because the request is from Russia (so things in the code may differ), but I only have this for cookies:

# Netscape HTTP Cookie File
# http://curlm.haxx.se/rfc/cookie_spec.html
# This file was generated by libcurl! Edit at your own risk.

.letitbit.net   TRUE / FALSE 1253169348 country RU
.letitbit.net   TRUE / FALSE 1221546947 access deleted
letitbit.net    FALSE / FALSE 1221546947 ref_full deleted
letitbit.net    FALSE / FALSE 1221546947 ref_site deleted
.letitbit.net   TRUE / FALSE 1253946948 reserv 19b668119b69af967c1e919c0b684e48

That is exactly what is stored with the CURLOPT_COOKIEFILE option.
