Moving VIEWSTATE and other hidden fields to the bottom of the page in

As we know that state of all ASP.NET controls is maintained __VIEWSTATE hidden field in encrypted format. By default this _VIEWSTATE HTML hidden field will be rendered at the top inside body tag (just below form tag). If we have lot of control data to be stored in ViewState then length of the viewstate will be more hence page will take time to load and also reduces rank in search engine as all the junk will be loaded at the top of actual content. So to make web page more search engine friendly and to make page render faster we may wish to move this __VIEWSTATE to the bottom of the page.
