Forms Authentication - Redirecting users to a Page other than Default.aspx

In this article I will explain how to redirect users to a specific page rather than the generic default.aspx upon successful authentication of the user.

While using ASP.NET Forms authentication, if we try to access a protected page, the user would be taken to the login.aspx page with the ReturnUrl parameter having the path for the originally requested page.

Once, the user's credentials are verified, the RedirectFromLoginPage method can be used to take the user back to the originally requested page.

However, if there is no specified ReturnUrl, then FormsAuthentication by default takes the user to the default.aspx page upon successful authentication.

If we do not have a default.aspx page or we want to take the users to our custom page etc., then we can use the Setauthcookie method to set the cookie and then redirect users to our desired page. The following code establishes the same.

// Once the user's entered credentials are verified //
if(Request.Params["ReturnUrl"] != null)
{
FormsAuthentication.RedirectFromLoginPage(txtUserName.text, false);
}
else
{
FormsAuthentication.SetAuthcookie(txtUserName.text, false);
Response.Redirect("CustomPage.aspx");
}

The above code first verifies whether there is any ReturnUrl parameter such that if exists, it should take to the originally requested page.

Else, it sets the authcookie and then redirects user to a custom page.

The txtUserName is the ID of the textbox which is used to capture the username.

This article applies to ASP.NET 1.0 & 1.1 Versions.

Thanks, I was stuck on this problem for a while, mostly because I didn't know about the ReturnUrl parameter. This explanation is great: short and to the point.

If your using .Net 2.0 or 3.0 you can just catch the "LoggedIn" event and redirect from there.

Protected Sub Login1_LoggedIn(ByVal sender As Object, ByVal e As System.EventArgs) Handles Login1.LoggedIn
If Request.Item("ReturnURL") = "" Then
Response.Redirect("tasclimb_default.aspx")
Else
Response.Redirect(HttpUtility.UrlDecode(Request.Item("ReturnURL")))
End If
End Sub

Just means you don't have to worry about calling any of the login methods.

# re: Forms Authentication - Redirecting users to a Page other than Default.aspx

I know this is a bit old now but, anyone got an idea how to fix missing query parameters?

For instance, if my returnurl is ReturnURL=mainpage.aspx?a=b&c=d

Response.Redirect(HttpUtility.UrlDecode(Request.Item("ReturnURL"))) will redirect me to mainpage.aspx?a=b (missing off the c=d bit).

Any help appreciated

Actually .. figured it out ..

string returnstring = Request["ReturnURL"];
for (int a = 1; a < Request.QueryString.Count; a++ )
returnstring += "&" + Request.QueryString.GetKey(a) + "=" + Request.QueryString.Get(a);

FormsAuthentication.SetAuthCookie(this.UserName.Text, true);
Response.Redirect(returnstring);

Can't help but feel it's a bit of a hack though. If anyone can come up with a "cleaner" way, it'd be appreciated.

Cheers,

Stu
