My case:

I have 2 folders Admin , Users

In Admin folder :main.aspx, admin.aspx

In users folder :usr.aspx,process,employee

In root :Login.aspx and Default.aspx

What i want to do : If username=admin and password=admin it redirect and access admin folder and if username=user and

password = user it redirect and access user folder ..

And users account can not access admin folder 

I used in webconfig the following:

<authentication mode="Forms">
      <forms name=".1" loginUrl="login.aspx"
      protection="All" path="/" timeout="30" />
    </authentication>
    <!--<authorization>
      <deny users ="?" />
      <allow users = "*" />
    </authorization>-->
  </system.web>

  <location path="Admin" >
    <system.web>
      <authorization>
        <deny users="?"/>
      </authorization>
    </system.web>
  </location>

  <location path="Users">
    <system.web>
      <authorization>
        <deny users="?"/>
      </authorization>

I try every code i have know like redirect page and  FormsAuthentication but it gives access to all folder and not eache
