Subject: Re: [PHP] cookies
This is sometimes a confusing issue for people, but remember that
cookies work like this:
1) client requests a resource from a Web server
2) Web server returns a response to the client including a request to
set cookies ("Set-Cookie" header)
3) client requests another page from the Web server and includes the
cookies ("Cookie" header) in the request
Some people want to know how they can tell whether the client accepts
cookies after step 1 (during the processing that results in step 2).
This is simply impossible.
However, you can adequately tell whether someone has cookies enabled
after you receive a second HTTP request from that person. On this
"second" page, simply test to see whether the cookie that you previously
set exists (isset is a good function for this). If it doesn't exist, the
client does not accept cookies. Some developers want this "check" to
appear as if it were performed on a single transaction and force the
client to make the second request.
