Sharepoint wss 3.0 authentication

I have developed one site in sharepoint wss3.0 when i type in the url i.e. http://testserver/default.aspx i am first asked username and password On successful 开发者_如何转开发login(I have created user from sharepoint central admin site) i am redirected to my site's login page.

then i have do login to access my site.

Now what i want to do is combine both logins i.e. when i login to my server using sharepoint user's username and password i want to be redirected to my site's home page. I should not be redirected to my site's login page

What should i do? Do i need to code in sharepoint's default login page present in _layouts directory? If yes how can i access login.aspx.cs ??

Plz help

Your application (assuming it's an ASP.NET application) needs to be deployed into sharepoint's _layouts directory, typically in a custom subfolder, in order to leverage session state and shared authentication.
