[TYPO3-english] TYPO3 and apache rewrites

[Pero Matic]

Can someone with knowledge of apache rewrites help me here please. I spend 
all day trying to debug it but no success. I have this rewriterule in 
virtual host section:

RewriteRule ^/classes(.*)$ /factory/planes/pilots/classes$1

So what i want to accomplish is when somebody writes:

http://mysite.com/classes/page

he gets the page located at:

http://mysite.com/factory/planes/pilots/classes/page

and address in his browser doesn't change - it stays 
http://mysite.com/classes/page

Now, after i put that rule in apache config, reloaded apache and accessed 
http://mysite.com/classes/page i get redirected to the http://mysite.com/ 
with apache status code 302 ???

If i make external redirect like this:

RewriteRule ^/classes(.*)$ /factory/planes/pilots/classes$1 [R]

everything works fine but address in browser is changed to 
http://mysite.com/factory/planes/pilots/classes/page which is not good for 
me.

So, anybody have an idea why 302 is sent and why am i being redirected to 
the /
Btw. i'm using CoolURI. THX!

Regards.
