There was a question of such a plan:
There is a site "site.ru" necessary for AJAX'u load the page with users, which is located at "site.ru/users/". I loaded it, but another question arises: how to make the url of the browser also change the url to "site.ru/users/", I just want to transfer the entire site to AJAX, but I think users will not like it , for example, they will not be able to give their friends a link to themselves or another page. Here are sites like vk.com and odkl.ru they also upload content to AJAX, otherwise it would be impossible to listen to music and move through the pages, and I want to notice that their URL changes. I ask the guru to help me.
