When you go to the site loading the page, when everything is loaded the rest of the page is loaded via ajax
xml.onload = function(){ if(xml.readyState===4&&xml.status===200){ $('article').html(xml.responseText); } }
If you look after it into the source code (click on the “Source code of the page”, and not the “Source code of the element”), then there is only the part that was loaded via ajax. And because of this, there are problems, for example, if you switch from this site to any other, and then press the button back, you can only see the piece of the page that was loaded via ajax. How to fix it?
