asp.net - What happens to the ViewState when I click back on the browser? -

i'm curious know happens viewstate on browse button.

does stay or page make new request?

viewstate remains no more .net implementation once render html , become normal hidden field sitting in html of page. when browse button , in of time page cache of browser , there no request server. there no way viewstate update without refreshing page , because @ end of day viewstate nothing hidden field .
