' The FollowRedirects property controls whether redirects
' are automatically followed.  The default behavior is to
' automatically follow redirects.

' Explicitly set FollowRedirects so that redirects are NOT automatically taken:
http.FollowRedirects = 0

success = http.HttpNoBody("GET","http://yandex.ru/",resp)

' The FinalRedirectUrl property will contain the redirect URL
' If FollowRedirects was equal to 1, then all of the 
' intermediate redirects (if any) would be followed until
' there were no more redirects.  However, because 
' FollowRedirects is not 1, FinalRedirectUrl contains
' the next redirect URL.

    ' For safety, prevent infinite loops by
    ' keeping a loopCount and only allows following a max 
    ' of 10 redirects:
    loopCount = loopCount + 1
