cprasad's and my purpose are same, so our responses will work. But just some diffrences;
"<ifmodule mod_rewrite.c="">" line checks wheter Apache's rewrite module is activated or not. If it is then it runs the code after that. The second one is that my rewritecond lines are less than cprasad's, but they all same conditions.By the way, i have just tested it before I wrote it.</ifmodule>
Just do it..
