http://stackoverflow.com/questions/19531183/set-cookie-on-multiple-domains-with-php-or-javascript


So how to change the FormsAuthentication cookie name and customer cookie name?


FormsAuthentication cookie name for nop commerce is NOPCOMMERCE.AUTH and located in:

\Presentation\Nop.Web\Web.config


   <authentication mode="Forms">
      <forms name="NOPCOMMERCE.AUTH" loginUrl="~/login" protection="All" timeout="43200" path="/" requireSSL="false" slidingExpiration="true" />
    </authentication>

Customer Cookie Name is Nop.customer and located in:

\Presentation\Nop.Web.Framework\WebWorkContext.cs


  private const string CustomerCookieName = "Nop.customer";

Shall i just rename those names , or should i make changes ? will this effect any plugins ?

Any help would be great.

I think you can make the FormsAuthentication Cookie name and customer cookie name saved in web.config(appsetting) file,and through deal with the web.config file to change what you want.
