How is the address bar at a large site like Amazon?

Good afternoon.
I was interested in the question of creation of pages on the site Avito. For example link to arbitrary item from the main page:
https://www.avito.ru/moskva/odezhda_obuv_aksessuar...
In the last part of the address string is a transliteration of the name of the product from the user and adds its id. I don't quite understand the mechanics, principle of operation of such sites. Actually a question:
When placing the product formed a separate html page? If not, how organized the structure of this and similar sites?
PS I realize that question may seem silly, sorry

No html pages are created, all stored in the database id is obtained from there.
I mean, I understand that this is purely the backend is? - gregory commented on April 4th 20 at 00:38
