Hello community, I have a web application in C # MVC and front in HTML with JS, I have a method to close session but when I return to the Login and press the "back" button of the browser I return to the session with all the data,
I share the code
Code Login HTML (FRONT):
<form method="post" action="@Url.Action("Admin", "Admin")">
<div class="form-group">
<input type="text" class="form-control input-lg" placeholder="Usuario" name="txtUs" />
</div>
<div class="form-group">
<input type="password" class="form-control input-lg" placeholder="Contraseña" name="txtPas" />
</div>
<div class="form-group col-md-6 col-lg-offset-3 text-center">
<input type="submit" class="btn btn-lg btn-info" value="Entrar" />
</div>
</form>
Code that validates the login (BehindCode):
private bool isSession(string u, string p)
{
bool isValid = false;
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, ConfigurationManager.AppSettings["ActiveDirectory"]))
{
//Valida si existe en el directorio activo
isValid = pc.ValidateCredentials(u, p);
}
if (isValid)
{
isValid = ma.isSessionValid(u);
}
return isValid;
}
In this way if it is valid it returns "true" and enters the index of the page, loading a session variable
Session["login"] = true
And to close the session I use the following code
public ActionResult LogOut()
{
Response.Cookies.Clear();
Response.AppendHeader("Cache-Control", "no-store");
Session.Clear();
// probé con esta linea pero tampoco funciona
// FormsAuthentication.SignOut();
Session.RemoveAll();
Session.Abandon();
return RedirectToAction("Login", false);
}
This return to the login, but when pressing the "back" key of the browser it returns to the previous page without going through the controller of said action, in ASP.NET I used
if(!IsPostBack)
//si la pagina esta regresando por postback cerrar sesión
Someone knows how I can avoid this PostBack from the server side, validate that the session is not recovered by giving it back, I have searched several pages and can not find a solution in
C # MVC, if they have any idea or article (English or Spanish) I can serve, I thank you.
