ASP.NET - Logout from code

[JackResteBienSurMaisSeraPas]

How do you logout from an account from the ASP.NET code?

How are you logged in? If it uses forms authentication, use

FormsAuthentication.SignOut

You might need to make sure that none of the pages are cached. If you're
using a master page, you can put the following code at the beginning of
Page_Load
Response.Expires = 60
Response.Expiresabsolute = Now() - 1
Response.AddHeader("pragma","no-cache")
Response.AddHeader("cache-control","private")
Response.CacheControl = "no-cache"

Hope that helps

This seems to work well. Is there a reason not to use it?

Sorry, I am new here. Don't know how to post a question, so using th Post Reply button:

When I logout, then login again, the application takes me to the login screen,
but the url is "localhost:3263/Login.aspx?ReturnUrl=%2fempty.aspx"
instead of just "localhost:3263/Login.aspx ". It makes me entering UID and PW twice. How can I remove the last part (?ReturnUrl=%2fempty.aspx) programmatically?
Thanks
