explain "session.cookie_domain"

[scrupul0us]

i have two session scripts going on the same server... in my ini file the session.cookie_domain is set to nothing

as such both scripts are talking to each other and i dont want that

so... on the fly ive spec'd this:

script 1:
ini_set("session.cookie_domain","/cart/");

script 2:
ini_set("session.cookie_domain","/cart_2/");

now neither will keep sessions

is this possible?

A cookie also has two other properties:

1. "domain" - A property that defines the domain of Web servers to which this cookie should be made available. Web browsers will send a cookie back to a Web server when the Web server matches its defined domain. Web browsers will never send back a cookie to a domain other than its defined domain.

For example, if a cookie's domain is www.google.com, the browser will send back this cookie to the server only when the browser is visiting www.google.com. The browser will never send back this cookie to www.yahoo.com.

To make a cookie available for all sub domains of a top level domain, set the domain property to the top level domain name. For example, if a cookie's domain is set to ".google.com", this cookie will be available to all google sub domains, like groups.google.com and gmail.google.com.

2."path" - A property that defines a Web server path to which this cookie should be made available. Web browsers will send a cookie back to a Web server when the Web server matches its defined domain, and the requested page matches its defined path. Web browsers will never send back a cookie to requested path other than its defined path.

Note that the defined path also includes all its sub paths. For example, if a cookie's domain is "www.amazon.com", and path is "/order/", then a browser will send back this cookie for requests like "http://www.amazon.com/order/checkout.html", and "http://www.amazon.com/order/report/invoice.html". But a browser should not send back this cookie for requests like "http://www.amazon.com/catelog/book.html".

Perhaps you should use [man]session_set_cookie_params/man to set it 😉

thanks to both:

session_set_cookie_params(3600,"","/cart/");

cleared it right up 😉
