How to increase Session timeout in C# MVC web application?

Question

Hi,

 

I am developing an web application in c# MVC, I am facing an issue in login session time. After few minutes login when I refresh the page or go to another page, it will logout and redirect to login page. I also set the "timeout="1440" in web.config file. Kindly go through following code.

 

WEB.CONFIG

<system.web>
<compilation targetFramework="4.5" tempDirectory="C:\Inetpub\vhosts\webdealsinv.com\tmp" />
<httpRuntime targetFramework="4.5" />
<authentication mode="Forms">
<forms loginUrl="Home/Login" timeout="1440" slidingExpiration="true" />
</authentication>
<roleManager enabled="true" defaultProvider="InvRoleProvider" cookieTimeout="1440">
<providers>
<clear />
<add name="InvRoleProvider" type="Inventory.Helper.InvRoleProvider" />
</providers>
</roleManager>
<httpHandlers>
<add path="*.less" verb="GET" type="dotless.Core.LessCssHttpHandler, dotless.Core" />
<add verb="GET" path="routejs.axd" type="RouteJs.RouteJsHandler, RouteJs" />
</httpHandlers>
<membership userIsOnlineTimeWindow="1440" />
<sessionState mode="InProc" timeout="1440" cookieless="false" />
</system.web>

LOGIN ACTION

[HttpPost, AllowAnonymous]
public ActionResult Login(InvUser invuser)
{
string result = objData.CheckUser(invuser);
if (result == "Success")
{
InvUser _invuser = objData.GetUser(invuser);
FormsAuthentication.SetAuthCookie(_invuser.UserID.ToString() + "|" + _invuser.FirstName, true);
return RedirectToAction("Index", "Admin");
}
else
{
ViewBag.Msg = "Invalid Email or password!";
return View();
}
}
