To restrict the domain of our cookies, we can use some Web.config settings.

HTML

<configuration>
  <system.web>
    <!-- Prevent access to cookies from other sub-domains -->
    <httpCookies domain="app1.*.com" />
  </system.web>
</configuration>

To restrict the path, we’ll need to add some server-side code. How we handle this is largely dependent on the structure of our application, but the example function below allows us to specify the path from a value in our Web.config when we set a cookie.

C#

private void SetCookie(string Key, string Value) 
{
    Response.Cookies[Key].Value = Value;
    Response.Cookies[Key].Path = _
    ConfigurationManager.AppSettings["UserDefinedCookiePathFilter"];
}

If we use this method to create all of our user-defined cookies, it will then allow us to restrict the path from our web.config like so:

HTML

<configuration>
  <appSettings>
    <add key="UserDefiniedCookiePathFilter"
      value="/VirtualDirectoryToFilter"/>
  </appSettings>
</configuration>
