Problem with subdomain module

I'm using subdomain module to rewrite user node http://www.example.com/node/nid to something like this - http://user.example.com/nid. When I vote for user node on site www.example.com - all ok, but when I try vote on user.example.com - nothings happends - I see only white block, without word "voted". I think, it's because the javascript generate link "vote" with url "/drupalit/count-vote/nid/1" and request GET http://www.example.com/drupalit/count-vote/nid/1 is not the same GET http://user.example.com/drupalit/count-vote/nid/1.
Can somebody help me with this problem? Any suggestion?
