401 Access denied....

Hello,
I am working with IIS 5.0. I am trying to access a webpage with necessary
accessibility credentials. Through the IIS log I observed that there are
totally 3 HTTP transaction happening to server my request. During first 2
transactions the response from server is "401 Access denied". The response
for the third transaction was "200 OK".

My doubt is why these 2 extra transactions are happening? Is there a way to
avoid this..?
Because this is causing network overhead by transferring nearly 8.46kb of
data (error pages) from server to client. So I want to avoid this. Please
share ur ideas with me.
Regards,
Prasad.

Prasad,

What you are describing is expected behavior from IIS. Each initial
request from a web browser is made anonymously, if IIS requires
authentication it will reply with a 401 to the client, and specify the
authentication methods supported (Basic, Integrated, etc.). The Client
(IE) then sends the appropriate authentication.

Please review the following article for more information on how IIS handles
Authentication.
