site url change by htaccess
===

this is my project site **http://readysolution.info/usjobs/test-category/?cpid=2&c_id=acc/**

i just needed show url by  **http://readysolution.info/usjobs/XXXX/YYYY/VVVVV**   instead of this 

**test-category/?cpid=2&c_id=acc/**

this is possible by .htaccess that my site url will be show by this new format . whetver will be display after /usjobs , it will be replace another word 

example : 1) if it have  **/usjobs/test-category/?cpid=2&c_id=acc/** , then it will be **usjobs/XXXX/YYYY/VVVVV**

2) 1) if it have  **/usjobs/test-category/?cpid=2** , then it will be **usjobs/DDDD/KKKKK**
