How to inhibit confirmation "form forwarding"?

I have a list of records where I do a search (via post) and after the result I select a record through a select, and I go to another page to edit that record. It turns out that when I finish editing this record I want to go back to the previous page "window.history.go(-1)" , the browser requires the confirmation of the form return, I know that this is a chrome pattern, but can you return without asking for this confirmation? I need to always use the method post.
