CODE EXAMPLE FOR JAVASCRIPT

replace url without reload js

// I want to change google.com in google.com/test.html in the address bar without reload

window.history.replaceState(null, '', '/test.html');

/*
replaceState(stateObj, unused)
replaceState(stateObj, unused, url)

stateObj :
The state object is a JavaScript object which is associated with 
the history entry passed to the replaceState method. The state object can be null.

unused :
This parameter exists for historical reasons, and cannot be 
omitted; passing the empty string is traditional, and safe against future 
changes to the method.

url (Optional) :
The URL of the history entry. The new URL must be of the same origin as 
the current URL; otherwise replaceState throws an exception.
