__VIEWSTATE encoding

TI was tapping my browser POST messages to a calendar, and noticed that the first message has an uncoded __VIEWSTATE, while the next messages seem to have it encoded (See bellow). How can a web server know that if a message has its __VIEWSTATE encoded or not? Because I didn't find anything in the headers about it. Would it be that a encoded message starts with "%2F", and an uncoded one not? Is there a RFC about it, if so which one?

Thanks,

Andre
