dhosek, you might be right, but i restarted my pc, cleaned my cache and it didn't work.
then i went ahead to try appending a random number besides its url and it worked just fine!
peculiarly though, im actually using IE 7.0.5730.11, while my friend is using 7.0.5730.11RC and he didn't had any prob without the random numbers. Firefox also worked fine.
