Whenever I click to return in the browser navigation appears the message to confirm the form resend and the error: ERR_CACHE_MISS.

How do I click to return to the previous page and do not ask for this confirmation?

I tried to put in the header:

<meta HTTP-EQUIV="Pragma" content="no-cache"> 
<meta HTTP-EQUIV="Expires" content="-1">

but it didn’t work, some hint?

    No, you do not understand, Soen is a site and Sopt is another, in no time I put in evidence the link to the Soen, just said that there is already a question in the OSpt on the subject, or be duplicate, does not agree?

This has no relation to PHP. It is the default behavior of the browser.

When a page submits data by the POST method, this data needs to be submitted again by going back to navigation. If the submission is canceled, the browser displays messages like this one below:
