This is good, because we have proven that cookies are working
correctly for you from within catalyst. The test application cannot
manipulate your other application's cookie because the test
application is running in a different location.
A web server running on http://localhost:3000 cannot view or
manipulate cookies for http://sin.my.office.com. This is for security
reasons. You would not want www.microsoft.com to be able to view or
delete your cookies for www.google.com, for example.
For your PHP application and your catalyst application to be able to
view/manipulate each others cookies, both applications must be
accessed on the same domain name and be setting their cookies into the
same 'path'. Please note... http://localhost and
http://localhost:3000 are considered different domain names, and will
not be able to interact with each other's cookies.
Cookies are programming language and server independent. All
languages and browsers follow generally the same rules. Once you
understand what these rules are, you will have a much better
understanding how cookies work in your application and how to
troubleshoot problems. A very good place to start is the
implementation section in this article:
