Flash detect browser back button problem

I have a flash detection page (index.html) that re-directs into my site or to a download request page. (content.html or detect.html)

My problem is when I’m in my site (content.html) and I press back on my browser, i obviously go back to the flash detection page (index.html) , then get re-directed back into my site again. (content.html)

Is there a script that controls your browsers back button that can skip my detection page and goto whatever page i was on before.

Any help would be much appreciated.

in the JS redirect use location.replace
