The initial URL is
https://robertbarakett.com/products/the-barakett-t-hoodie?option1=Blue+night&option2=S
I traced the HTTP requests. It only does 1 redirect: from
https://robertbarakett.com/products/the-barakett-t-hoodie?option1=Blue+night&option2=S
to
https://robertbarakett.com/products/the-barakett-hoodie-black?option1=Blue%20night&option2=S.
However, the final URL in the address bar is
https://robertbarakett.com/products/the-barakett-hoodie-black?variant=31966791729263.
I read about changing URL without reloading page:
Since there is no navigation history after loading the web page, it rules out window.history.pushState
. Maybe it uses window.history.replaceState
? I did a search in the page's source code, didn't find any use of replaceState
. So how to verify whether it uses replaceState
or other techniques?
