Problem - jQuery post method including mod_rewrite

Hi all,

I have problem with sending post request via jQuery method. Some explanation:

!!! This case is working on my private PC perfectly fine.

I'm using simple post method to send information to php script:
  1. $.post('do.php', {name: "John", age: "25"} , function(data){
          alert(data);
    });
PHP Script
  1. <?php
  2.       echo 'post request:';
  3.       print_r($_POST);
  4. ?>      

It's preatty simple... 
As I wrote on my PC is working fine! Unfortunately I uploaded it to 1ana1 servers.... and this is pain in the ass!! :)
When I'm using it on serwer I just get text "post request" and empty array => Array()

Can anybody help with this issue ? what can be wrong ?

I'm using mod_rewrite on my PC and 1and1 serwer. I'm getting text back so I belive that the address is fine....

.... anybody...

Cry for help..
