Back to previous page in Ajax Call

acutally i have a working Ajax Call that get me back after succeed to a static defined Site.

$.ajax({ 
            url: 'myPage.php',
            type: 'get', 
            data: {TestaufstellungID:TestaufstellungID, Datum: Datum}, 
            dataType: 'text',

            success:function(data){ 

                    window.location = "staticPage.php";
                 console.log('SQL Eintrag Erfolgreich Aktuallisiert');
     },
     error: function(jqxhr, status, exception) {
         console.log(exception);


            }
        });

It works fine with window.location but i want a dynamic site, back to this site where the use came from, like in PHP:

header('Location: ' . $_SERVER['HTTP_REFERER']);

Please dont give me answer like history.go(-1); becasue i dont want cached sites. Should be do the same like the php code, because in some cases i need the page URL with all string (Get-Method).

Thx for you help.

EDIT: My reference Post, to understand the step by step page working order, i want to be back all in all to the first step(page) but this page is not always the same one.
