Crashed PHP cookie (PHPSESSID=PHPSESSID=XXXXX)

Pls help me. I have the problem with crashed php session in case header redirect: For example - user get any page: https://example.com/any_pages/some_page/ But I want redirect him to: https://example.com/any_pages/some_page/ I do this by using:

header('Location: https://example.com/any_pages/some_page/', true, '301');

I get cookies just before redirect and it all - ok. But at the very beginning of the receiver file I get cookies and it broken:

$_COOKIE:
Array
(
    [language] => language=ru
    [currency] => currency=RUB
    [PHPSESSID] => PHPSESSID=c8fd0e0d100a5d214ee99f205d6d0ff2
)

in result - session crashed. Of course I can parse cookie and restart session, but it`s not right (may be).

May be you know: How do I save the session (and cookie (in cookie i save product_cart)), correctly?
