Different forums are filled with the questions regarding how to manually implement cookies for login or in other words how to implement "Remeber me" option.
Following is the code that will give the idea of how to achieve this task.
Controls used
1. TextBox, ID = TbUserName
2. TextBox, ID = TbPassword
3. CheckBox, ID = CbRememberMe
4. Button, ID = BtLogin
5. LinkButton, ID = lbSignout
------------------If you are using VB.Net-------------------------
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
'Check if the browser support cookies
If Request.Browser.Cookies Then
'Check if the cookies with name PBLOGIN exist on user's machine
If Request.Cookies("PBLOGIN") IsNot Nothing Then
'Pass the user name and password to the VerifyLogin method
Me.VerifyLogin(Request.Cookies("PBLOGIN")("UNAME").ToString(), Request.Cookies("PBLOGIN")("UPASS").ToString())
End If
End If
End If
End Sub
Protected Sub BtLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs)
'check if remember me checkbox is checked on login
If (Me.CbRememberMe.Checked) Then
'Check if the browser support cookies
If (Request.Browser.Cookies) Then
'Check if the cookie with name PBLOGIN exist on user's machine
If (Request.Cookies("PBLOGIN") Is Nothing) Then
'Create a cookie with expiry of 30 days
Response.Cookies("PBLOGIN").Expires = DateTime.Now.AddDays(30)
'Write username to the cookie
Response.Cookies("PBLOGIN").Item("UNAME") = Me.TbUserName.Text
'Write password to the cookie
Response.Cookies("PBLOGIN").Item("UPASS") = Me.TbPassword.Text
'If the cookie already exist then wirte the user name and password on the cookie
Else
Response.Cookies("PBLOGIN").Item("UNAME") = Me.TbUserName.Text
Response.Cookies("PBLOGIN").Item("UPASS") = Me.TbPassword.Text
End If
End If
End If

Try
'If login credentials are correct
'Redirect to the user page
'else
'prompt user for invalid password

Catch ex as System.Exception

End Try
End Sub
