Apache mod_rewrite serves same content for different urls

Question

I have strange issue, I cant find the answer nowhere. I have set apache2 server with mod_disk_cache. I have strange issues where I get same page for different URL's. Let's say that I visit page via homepage - it works fine. If I go to the article, from the homepage, I can see the article - works fine. Back to the homepage - works fine. From the homepage to some other article - ISSUE: I still have content of the home page.

I'm my development server everything works well. On the production server I get those issues.

Some details:

DEV server: Windows 7 apache 2.2.17 php: 5.3.4

PRODUCTION server: centOS apache 2.2.3 php: 5.2.9
