Discussion
Context.Security.Login() logs in a user and optionally letting you redirect the successful login to a specific page and set the authentication cookie's lifetime. When login is successful the Context.Security.CallResult.ReturnDataValue will contain the redirect page URL. Check Context.Security.CallResult.Success before using the return value.
Example: Redirecting After Login
Upon successful login, the user can be redirected to another page. The Context.Security.CallResult object has a property called ReturnDataValue that contains the page to redirect the user after login. This property will either contain the default redirect page defined in security settings or contain the redirect page specified when the login method was called. If login fails or the redirect behavior is set to "current page", Context.Security.CallResult.ReturnDataValue will be blank.
The example below demonstrates how to peform a redirect using Context.Security.CallResult.ReturnDataValue:
context.Security.Login(Username,password,"index.a5w") if context.Security.CallResult.Success if Context.Security.CallResult.ReturnDataValue <> "" ' has a redirect response.redirect(Context.Security.CallResult.ReturnDataValue) end if end if
Example: Redirecting After Login with JavaScript
The redirect can also be made using JavaScript (returned by an Ajax Callback):
if Context.Security.CallResult.ReturnDataValue <> "" ' has a redirect javascript = "window.location='"+Context.Security.CallResult.ReturnDataValue+"';" end if
