hello,
That script redirect to another site, but there is no <a href="... </a>
command
this code i have found in html source:
<SCRIPT language="JavaScript">
o =
'0x6c,0x6f,0x63,0x61,0x74,0x69,0x6f,0x6e,0x20,0x3d ,0x20,0x27,0x68,0x74,0x74,
0x70,0x3a,0x2f,0x2f,0x77,0x77,0x77,0x2e,0x74,0x72, 0x61,0x76,0x65,0x6c,0x77,0
x65,0x62,0x2e,0x70,0x6c,0x27,0x3b';
.................................. eval(js_code);
</SCRIPT>
What means these values? '0x6c,0x6f,0x63,0x61,0x74...., I am very
novice but i know that javascript is not server side. How to debug this
symbols and see the source of that code? Is that possible?
Thank for answers

Javascript can be used for a number of purposes, including
server-side.
How to debug this symbols and see the source of that code? Is that possible?
These scripts are pretty much a waste of time since they decode
themselves. There will either be a document.write or an eval that
calls document.write that writes the resulting script. Note: some
people add extra ones that are fake. I usually just add <textarea
rows="30" cols="80"> ... </textarea> around whatever it writes so the
source shows up in a textarea.

so that script is server side? Am i right? And is it possible to decode
that
'0x6c,0x6f,0x63,0x61,0x74,0x69,0x6f,0x6e,0x20,0x3d ,0x20,0x27,0x68,0x74,0x74, 0x70,0x3a,0x2f,0x2f,0x77, signs?

Hey Dany,
Those are hex numbers. Numbers with base 16, instead of 10 like we're
used to. The 0x just means that they are hex numbers.
An example for getting the value of the hex number 0x6c. Remove the 0x.
The 6 is the most significant number, so we need to multiply that by 16.
6*16 = 96, then we have the C left, which is the least significant. We
need to add that to the 96. C in hex is 12. 96+12 = 108. So 6c is
decimal 108. This code is much used because one digit is exactly 4 bits,
so two digits is exactly one byte. Easy for programmers to use once
you understand it. The numbers we are used to are really exactly the
same build up as hex numbers, except thats its base 10.
Hex: 0x6C = 0x6*0x10 + 0xD (note that 0x10 != 10, but 0x10 = 16)
Dec: 63 = 6 * 10 + 3
Some good examples: 0x0 = 0, 0x10 = 16, 0x20 = 32, 0xff = 255 (familiar
numbers?)
the value js_code contains the code. Its probably derives from the hex
code in o. try alert(js_code) and you'll see the actual code. It seems
to be some kind of protection for hiding the URL.
Good luck,
Vincent

No, no, yes. Read on character encoding.
