Url rewriting and linking

Hi Mates..

I m New to Drupal n creating static site in it. I m Looking for url rewriting like my page name should be

like student/newadmissiondetails.html

i m using clean url so it showing me my full path like www.xyz.com/student/newadmissiondetails.html

but on this page i m not able to link other pages like process/admission.html

on page student/newadmissiondetails.html links are student/process/admission.html which is wrong. it should be process/admission.html

plz help me how can i do this.
