A Question about Setting "Apache RewriteEngine"

i wrote this question to the web forum, but no one asked back.
so i describing the 'RewriteEngine' problem for you to suggest me.(even direction for the solving)

i think gettering the answer from the "world of blog" would be a great&new experience.

======CONTENT================
i uploaded the '.htaccess' file to the web-directory(web accessible) of webserver with this details.

--
RewriteEngine on
RewriteCond %{HTTP_HOST} ^[^.]+\.freeusb\.info
RewriteRule ^(.+) %{HTTP_HOST}$1 [C]
RewriteRule ^([^.]+)\.freeusb\.info(.*)$ /home/hosting_users/frontjang/$1/$2
--

on my expectation,
1. when i entered the page "http://www.freeusb.info/index.htm" , it redirects to the "/home/hosting_users/frontjang/www/index.htm"
2. when i entered the page "http://data.freeusb.info/index.htm" , it redirects to the "/home/hosting_users/frontjang/data/index.htm"
3. when i entered the page "http://subdomain.freeusb.info/blog/index.php" , it redirects to the "/home/hosting_users/frontjang/subdomain/blog/index.php "

the first case acts well. but the others gets the errors as follows
(i can't view the apache error log - the admin wouldn't admit viewing the logs. -for the security reasons)
