Hi,
I appear to have a problem where the user is not kicked back to the
forms authentictation url when they post a webform, via a get, that
results in a long url due to viewstate. Instead they get the error at
the end of the post
Web.Config:
<authentication mode="Forms">
<forms path = "/" loginUrl = "View/Login.aspx" timeout="1"
protection="All" name="DiscAccept"/>
</authentication>
<authorization>
<deny users = "?" />
</authorization>
URL:
http://localhost/App/View/Login.aspx...AyOjUwLjAxMjQz
zc7Pj47Oz47Pj47Pj47Pu%2BxizxVhIWgw4i0JUECemLiNzSQ& Button1=Button
Any Ideas?
Thanks
Jerry
