Back to previous page in e-commerce site

Question

I am working with e-commerce site, where user can navigate using filters like category, then subcategory, then Brand and finally product. so the process flow is

product.php?catid=1&subcatid=11&brandid=12&prodid=111

Now the problem is, when I am clicking on Back button of browser, it asks for confirm form re-submission. But what I want is, it should directly go to Brand filter. I mean to

product.php?catid=1&subcatid=11&brandid=12

Any kind of help is really appreciated.
