Throw System.UnauthorizedAccessException ?

I want to block access to my ASP.NET 2.0 web page if the time is
between 3:00 and 4:00. I know how to do the date math - is it proper
to throw an UnauthorizedAccessException at that time? I want to pass
an "access denied" back to the browser but am not sure if that will
work.

Thanks

re: Throw System.UnauthorizedAccessException ?


Another idea could be redirecting the user to a custom page showing
access denied message.

re: Throw System.UnauthorizedAccessException ?



I don't want to do that because a crawling bot might be hitting the
page too. I want to show unauthorized access early in the HTTP
communication process, low level. Can I do that from within a ASPX
page?

re: Throw System.UnauthorizedAccessException ?


I would actually suggest against sending a 403 or some other HTTP
access denied because the crawlers may act adversly. The redirection
is a good idea. The crawlers will not care as long as it is a
temporary redirect, not a permanent one. Try something like this:

Response.StatusCode = 302
Response.Status = "302 Moved Temporarily"
Response.AddHeader("Location", "/Unauthorized.aspx") ' Note: "/
Unauthorized.aspx" is just an example
Response.End()

Hope this helps.

Surley HTTP Status 401 Unauthorized would be better, along with response.end
(no redirect, the browser will just say unauthorized )

re: Throw System.UnauthorizedAccessException ?



So throwing an UnauthorizedAccessException is not the same as sending
a 401 in the HTTP Response?

re: Throw System.UnauthorizedAccessException ?



If /unauthorized.aspx does not exist, then body content will be sent
to the browser "page not found" or something. And if it does exist,
body content will still be sent to the browser. Is there a way to make
the client hang in a suspended state forever to keep a bot from ever
getting anything substantial from the server? What do you think of
activating one of the HTTP authentication schemes to put up a logon
box, that would make the bots go away and people too.
