kohana 3.2没有得到'get'请求

After the transfer to a new server I'v got issue with get request.

for example

class Controller_Main extends Controller {
  public function action_testrequest()
  {
    echo "<pre>";
    print_r($_GET);
    $this->auto_render = FALSE; // don't use layout
  }
}

and url my-site/main/testrequest?query=test returns empty array

at the same time my-site/test.php?query=test with content

<pre>
<?php
print_r($_GET);

returns

Array
(
[query] => test
)

Why is that?

I see the reason is in kohana, but I cannot find it.

Any clue?

The issue was with .htaccess

Solved replacing this:

RewriteRule .* index.php/$1 [PT]

instead this:

RewriteRule .* index.php/$1 [PT,L]

This discussion helped me.
