Igor, thank you very much for your support. My english is really bad but i will do my best to ask my question on the right way. I have around 100 sites and all of them use mod_rewrite. There are too many rules. Is there any way i can convert all these rules working with rewrite into nginx? Is there any other easier way that i can transfer all these sites to work under nginx. The Apache server makes the machine to work way too heavy and i want to change it with nginx-my experienced so far show me that it is at least twice lighter.

Thank you
