如何强制页面仅在每次访问时刷新一次

Question

I've tried about 10 different ways that I found on here and the only found one that works close. I'm having an issue with Hostgator all of a sudden not displaying new content on php pages that access and display data from text files and/or databases. These pages have been in place for years working fine and continue to do so on other hosts. The only problem I have with the script below is that it won't refresh the page on the first visit. After the first refresh it will then show changes. I need something that will refresh all the time regardless of a visitors history or browser settings.

<script type='text/javascript'>
     (function()
     {
        if( window.localStorage ) {
           if( !localStorage.getItem( 'firstLoad' ) ) {
               localStorage[ 'firstLoad' ] = true;
               window.location.reload();
            }
          else
              localStorage.removeItem( 'firstLoad' );
        }
    })();

</script>

you can use a cookie:

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

(function()
{
    var value = readCookie('mycookiereload');
    if(value == null)
    {
        var date = new Date();
        date.setTime(date.getTime()+(3600000));
        var expires = "; expires="+date.toGMTString();
        document.cookie = "mycookiereload=1"+expires+"; path=/";
        alert("going to reload");
        window.location.reload();
    }
    else
    {
        var date = new Date();
        date.setTime(date.getTime()-(3600000));
        var expires = "; expires="+date.toGMTString();
        document.cookie = "mycookiereload="+expires+"; path=/";
        alert("kill cookie");
    }
})();

this will reload the page once. everytime you visit a page, it checks the cookie, if it's not there, creates and reloads, if it's there, removes the cookie to get the same effect again.
