Unfortunally I think the solution with history.back is not gonna work with my problem because I initially didn't count on situation where users would come to login page directly (from bookmark or by typing in).

I would never catch this problem on my own tho, and want to thank jdiehl who point it out in this thread http://forum.x-cart.com/showthread.php?t=52514 .

I am currently waiting for reply from QT regarding this issue and will let everyone know as soon as I'll get any news
